NHTSA Interpretation File Search
Overview
NHTSA's Chief Counsel interprets the statutes that the agency administers and the standards and regulations that it issues. Members of the public may submit requests for interpretation, and the Chief Counsel will respond with a letter of interpretation. These interpretation letters look at the particular facts presented in the question and explain the agency’s opinion on how the law applies given those facts. These letters of interpretation are guidance documents. They do not have the force and effect of law and are not meant to bind the public in any way. They are intended only to provide information to the public regarding existing requirements under the law or agency policies.
Understanding NHTSA’s Online Interpretation Files
NHTSA makes its letters of interpretation available to the public on this webpage.
An interpretation letter represents the opinion of the Chief Counsel based on the facts of individual cases at the time the letter was written. While these letters may be helpful in determining how the agency might answer a question that another person has if that question is similar to a previously considered question, do not assume that a prior interpretation will necessarily apply to your situation.
- Your facts may be sufficiently different from those presented in prior interpretations, such that the agency's answer to you might be different from the answer in the prior interpretation letter;
- Your situation may be completely new to the agency and not addressed in an existing interpretation letter;
- The agency's safety standards or regulations may have changed since the prior interpretation letter was written so that the agency's prior interpretation no longer applies; or
- Some combination of the above, or other, factors.

ID: 86-2.4OpenTYPE: INTERPRETATION-NHTSA DATE: 03/04/86 FROM: AUTHOR UNAVAILABLE; Erika Z. Jones; NHTSA TO: Larry Alexander TITLE: FMVSS INTERPRETATION TEXT:
Mr. Larry Alexander Senior Product Manager Consumer Products Division Tuck Industries, Inc. Lefevre Lane New Rochelle, NY 10801
Dear Mr. Alexander:
This is in reply to your letter of October 1, 1985 asking whether any of your pressure sensitive tapes packaged for the automotive aftermarket are subject to any regulations of the National Highway Traffic Safety Administration. You have been asked by one of your customers to certify that your tape meets all applicable Federal motor vehicle safety standards and other regulations. You provide four types of tapes: lens repair tape (for temporary use until a broken lens is replaced), hose repair tape (for temporary repair of leaks in water hoses), clear patch tape (for repair of upholstery), and carpet tape (used to hold carpets in place). This agency has jurisdiction over items of motor vehicle equipment, which are defined in part as:
"any system, part or component of a motor vehicle as originally manufactured or any similar part or component manufactured or sold for replacement or improvement of such system, part, or component or as any accessory or addition to a motor vehicle...." Your tape could be regarded as an "addition" to a motor vehicle but even assuming that it is an item of motor vehicle equipment, there are no Federal motor vehicle safety standards that would apply to it. Therefore, no manufacturer certification is required, and you may so inform your customer. Further, any such certification could be viewed as a violation of the National Traffic and Motor Vehicle Safety Act by being certification that is false and misleading in a material respect, stating compliance with standards which are, in fact, non-existent.
Sincerely,
Erika Z. Jones Chief Counsel
October 1, 1985
Office of the Chief Council National Highway Traffic Safety Adm. Washington, DC 20590

ID: 77-1.15OpenTYPE: INTERPRETATION-NHTSA DATE: 02/02/77 FROM: AUTHOR UNAVAILABLE; F. Berndt; NHTSA TO: Department of California Highway Patrol TITLE: FMVSS INTERPRETATION TEXT: This is in reply to your letter of December 16, 1976, which raises several questions with respect to motor vehicle lighting and Motor Vehicle Safety Standard No. 108. First I want to comment upon this statement: "A NHTSA representative recently indicated that the standard applies to 'original equipment' replacement items such as lenses and lamps designed for specific year model vehicles, but does not apply to 'aftermarket' lighting equipment that is not manufactured for a particular vehicle but is sold for general use on any vehicle." This is not entirely true. Standard No. 108 applies in pertinent part "to lamps, reflective devices, and associated equipment for replacement of like equipment or vehicles to which this standard applied." The standard applies to motor vehicles manufactured on or after January 1, 1972. Thus, any replacement of an original equipment item specified by Standard No. 108 must meet original equipment requirements. This not only includes lenses and lamps, such as parking lamps and tail lamps designed for specific year model vehicles but also lighting equipment sold for general use, such as headlamps, clearance lamps, and identification lamps, whose dimensions do not vary over the years. Your first question is: "1. Some aftermarket-type manufacturers produce lamps and other devices that are shown in their catalogs for universal use with no vehicle model being mentioned. Some of these lamps may also be supplied to producers of motor homes, boat trailers, horse trailers, commercial trucks and trailers, etc., as original equipment on those vehicles. Does the fact that a portion of the production of a particular lamp is sold as replacements for the original equipment mean that the other portion sold for use on any 1976 truck or trailer is also governed by Standard No. 108 with respect to the "aftermarket" sales?" The answer is yes, as I explained in my preliminary remarks about the applicability of Standard No. 108 to all replacement equipment. "2. In the past, motor vehicles were equipped with round-type sealed beam units. Now that rectangular units are available, some owners are interested in converting the original round headlamps to the rectangular type. Are these rectangular sealed beam units and conversion kits sold to the user considered replacement of like equipment on vehicles to which this standard applies or are they subject to state regulations?" We construe the words "like equipment" broadly. If one headlighting system is being replaced with another, the replacement headlighting system must meet the requirements of Standard No. 108, even though its configuration differs from that of the original. Obviously, a State may also regulate sale of this equipment if its requirements are identical with the Federal ones. "3. Manufacturers of nonsealed, quartz-halogen headlamp units are energetically promoting the sale of the units in many areas of the country. These lamps differ considerably from the sealed beam units originally required on late model vehicles at the time of first sale. Do these lamps fall within federal jurisdiction or are they subject only to state regulation?" Quartz-halogen headlamps sold in the aftermarket, intended as replacement for headlamps that comply with Standard No. 108, must also meet Federal requirements. If the lamps do not conform, not only would their sale be a violation of the National Traffic and Motor Vehicle Safety Act (Section 108(a)(1)(A), but the removal of sealed beam headlamps by the seller or a motor vehicle repair shop to facilitate the installation of the nonconforming ones would also be a violation of the Act (Section 108(a)(2)(A). "4. A number of items such as flashers, school bus warning lamps, and headlamp units are sold for universal use. They might be part of a new vehicle at time of sale or be sold separately as a replacement for vehicles manufactured both before and after 1972 or as an addition to such vehicles. Does this mean that dual regulations are permissible with NHTSA setting standards for the production items used as original equipment replacement and the states setting standards and requiring approval for the identical item for usage not regulated by the Federal Motor Vehicle Safety Standards?" It is NHTSA's position, as explained earlier, that if an item of lighting equipment "sold for universal use" is capable of replacing equipment on a vehicle manufactured on or after January 1, 1972, then it must meet Standard No. 108, and a State may also regulate it in an identical manner. You also asked our advice "on the problem of not being able to recognize whether a particular item has been certified or not." As an alternative to the DOT mark permitted by S4.7.2 of Standard No. 108, replacement lighting equipment may be certified in two other ways. Pursuant to Section 114 of the Act certification "may be in the form of a label or tag on such item or on the outside of a container in which such item is delivered." Thus, access by a State enforcement officer to corporate records is not required. If an item subject to Standard No. 108 is not marked "DOT," if it bears no certification label or tag, and if its container is unmarked, then it has not been certified as required. I hope this answers your questions. SINCERELY, DEPARTMENT OF CALIFORNIA HIGHWAY PATROL December 16, 1976 File No.: 61.A218.A3107 Frank Berndt Acting Chief Counsel National Highway Traffic Safety Administration The finding of the U.S. District Court in Pennsylvania against state requirements for presale approval of items of motor vehicle equipment regulated by the Federal Motor Vehicle Safety Standards, if upheld, will eventually result in all states curtailing their approval programs. The question then becomes one of determining specifically which items of equipment are federally regulated. The answer appears clear-cut with respect to equipment standards that apply to an individual item such as brake hoses, safety glazing, emergency triangular reflectors, seat belts, etc. It is not so clear with respect to the part of Standard No. 108 which applies to "lamps, reflective devices, and associated equipment for replacement of like equipment on vehicles to which this standard applies". A NHTSA representative recently indicated that the standard applies to "original equipment" replacement items such as lenses and lamps designed for specific year model vehicles, but does not apply to "aftermarket" lighting equipment that is not manufactured for a particular vehicle but is sold for general use on any vehicle. It is important to us to know whether or not we may have misinterpreted the discussion. We are investigating how best to amend our laws, regulations, and approval procedures if the Pennsylvania decision becomes binding upon all states. The following questions have arisen with respect to which items of lighting equipment are regulated by Standard No. 108 and which are not: 1. Some aftermarket-type manufacturers produce lamps and other devices that are shown in their catalogs for universal use with no vehicle model being mentioned. Some of these lamps may also be supplied to producers of motor homes, boat trailers, horse trailers, commercial trucks and trailers, etc., as original equipment on those vehicles. Does the fact that a portion of the production of a particular lamp is sold as replacements for the original equipment mean that the other portion sold for use on any 1976 truck or trailer is also governed by Standard No. 108 with respect to the "aftermarket" sales? 2. In the past, motor vehicles were equipped with round-type sealed beam units. Now that rectangular units are available, some owners are interested in converting the original round headlamps to the rectangular type. Are these rectangular sealed beam units and conversion kits sold to the user considered "replacement of like equipment on vehicles to which this standard applies" or are they subject to state regulations? 3. Manufacturers of nonsealed, quartz-halogen headlamp units are energetically promoting the sale of the units in many areas of the country. These lamps differ considerably from the sealed beam units originally required on late model vehicles at the time of first sale. Do these lamps fall within federal jurisdiction or are they subject only to state regulation? 4. A number of items such as flashers, school bus warning lamps, and headlamp units are sold for universal use. They might be part of a new vehicle at time of sale or be sold separately as a replacement for vehicles manufactured both before and after 1972 or as an addition to such vehicles. Does this mean that dual regulations are permissible with NHTSA setting standards for the production items used as original equipment replacement and the states setting standards and requiring approval for the identical item for usage not regulated by the Federal Motor Vehicle Safety Standards? Lighting equipment subject to FMVSS No. 108 is not required to be marked in any way with the manufacturer's name or model number nor is a DOT certification symbol required. Without such markeings and symbol, neither a potential customer nor an officer inspecting devices offered for sale at retail outlets has any way of knowing whether a particular device is one that has been certified by the manufacturer as meeting the standard or whether it is a bootleg product that is locally produced or imported without complying with the standard. Neither the customer nor the officer has access to the store's records to determine whether or not the manufacturer included the federally-required certification with the shipment. If the federal standards totally preempt the state requirements on lighting devices, manufacturers will no longer need to place any markings on their products, since the federal standards make no such requirement. It, therefore, becomes impossible for any local agency to attempt to enforce the federal standard and, in view of the limited enforcement personnel in NHTSA, it means that anyone can sell almost anything he wants with little change of being detected by NHTSA and being prosecuted by the Department of Justice. We would appreciate your answers to the above questions and your advice on the problem of not being able to recognize whether a particular item has been certified or not. WARREN M.

ID: 13415.ztvOpen Ms. Ana S. Salcedas Dear Ms. Salcedas: This responds to the letter that you and Mr. Silva sent us on December 14, 1996. We are sending a copy of our reply to Mr. Silva at his Philadelphia address. You have asked our "assistance in ensuring that the patent [for the Auto Brake Light] meets the requirements for Code 571.108." The patent application indicates that the Auto Brake Light is a message-sending device that can take several forms. In one application, the center highmounted stop lamp can display the message "STOP". In another form, the left hand stop lamp, the center highmounted stop lamp, and the right hand stop lamp can display, one word to a lamp, the message "SLOW DOWN NOW". We assume that the lower stop lamps could also display the message "SLOW DOWN." The application states that "[o]ptimally, the present invention may be used with retrofitted light assemblies that are attached to a vehicle after its original manufacture." Under our basic regulatory statute, 49 U.S.C. Chapter 301, a motor vehicle must conform with all applicable Federal motor vehicle safety standards at the time it is sold and delivered to its initial purchaser. This means that, if the vehicle is modified after manufacture and before such sale, it must continue to comply with the Federal safety standards after the modifications. Motor Vehicle Safety Standard No. 108 Lamps, Reflective Devices and Associated Equipment, 49 CFR 571.108, permits the addition of supplementary lighting devices at the time of initial manufacture or before initial sale provided that they do not impair the effectiveness of lighting equipment required as original equipment by Standard No. 108. As noted above, in one form of your invention, the center highmounted stop lamp can display the word "STOP." Figure 10 of Standard No. 108 establishes minimum candela intensity values that must be met at individual test points on the lamp, or the sum of such test points within zones. If any portion of the word "STOP" obscures the light at any individual test point so that the zone total falls below the minimum sum specified for the zone, that obscuration would create a noncompliance with Standard No. 108, and the retrofitted lamp would not be permissible. In addition, visibility of the center stoplamp signal must not be impaired by any part of the vehicle including the word "STOP" from test points 10U to 5D and from 10L to 10R, unless the lamp is designed to comply with all requirements when the obstruction is considered. If the letters can be arranged so that the lamp continues to comply, as discussed above, we do not believe that the word "STOP" would impair the effectiveness of the center stop lamp. On the other hand, we believe that the message "SLOW DOWN" or "SLOW DOWN NOW" when placed on the lower stop lamps could create a momentary distraction, which would impair the effectiveness of the stop lamp system when used to signal that the vehicle is stopping. This aspect of your invention would not be permitted by Standard No. 108. Once a motor vehicle is sold, 49 U.S.C. Chapter 301 prohibits manufacturers, dealers, distributors, and motor vehicle repair businesses from making inoperative any device or element of design installed in accordance with a Federal motor vehicle safety standard. We view the phrase "making inoperative" in this case as the equivalent of creating a noncompliance with Standard No. 108. This means that the persons named in the previous sentence may not retrofit a center lamp with the word "STOP" if it obscures any of the required test points. Further, it means that such persons may not retrofit vehicles with lamps spelling "SLOW DOWN NOW." Because existing lamps are designed to meet the required test points with an unobscured lens, it is almost a certainty that lamps on vehicles in use would become noncomplying if retrofitted with letters forming words such as "STOP" and "SLOW DOWN NOW." You will note that the prohibition discussed above does not extend to the vehicle owner who, under the statute, may create a noncompliance in his or her vehicle without violating Federal law. But a vehicle modified by its owner remains subject to the laws of the States in which it is registered and used. We are unable to advise you on State laws that may affect your device, and recommend that you contact the Department of Motor Vehicles of the States where you intend to market it. We offer no opinion on the validity under Federal law of the other patented lighting devices discussed in the application. If you have any questions, you may contact Taylor Vinson of this Office (202-366-5263). Sincerely, John Womack cc: Mr. Armenio N. Silva ref:108 |

Route 1 Box 190 Gadsden AL 35901; Dear Mr. Cox: This is in reply to your letter of July 8, 1987, with respect t whether a lighting product you intend to market is 'in violation of any federal regulation when mounted on a motor vehicle.'; You describe your product as a 'lighted decal' which can be mounted i the rear window of any car or pick-up truck, and the photographs you enclosed show it mounted in the center of the rear window of a pre-1980 model Seville.; The decal will be wired into the brake system and when activated by th brake 'only the letters in the decal will be lighted.' You state further that although the letters will appear red to an observer 'this product is not designed nor will it be marketed as a brake light or a tail light.'; In our opinion, your product may or may not be in violation of Federa requirements depending upon the following uses. The product does not appear to be intended as a substitute for the center highmounted stop lamp that has been standard equipment on passenger cars manufactured on or after September 1, 1985. Indeed, it could not be so used unless it met all requirements for such a lamp. The principal requirements are that such lamps have a minimum of 4 1/2 square inches of illuminated lens area, that it meet specified photometrics at 13 test points, and that it produce a signal visible from 45 degrees from the right to the left and from five degrees up to five degrees down. If your device does not meet these requirements, removal of the lamp and replacement with your device would violate a prohibition of the National Traffic and Motor Vehicle Safety Act against rendering inoperative equipment installed in accordance with a Federal motor vehicle safety standard, in this case Safety Standard No. 108, *Lamps, Reflective Devices, and Associated Equipment*. However, a dealer could install it on a new pick-up truck, or to one side of the center lamp in a new passenger car before their initial sale, provided the device did not impair the effectiveness of the rear lighting equipment required by Standard No. 108, and the device could be installed on some vehicles in use (cars built before September 1, 1987, and any pick-up) provided that it did not render inoperative in whole or in part other required rear lighting equipment.; By this we mean that the device appears allowable for these vehicle under Federal law provided that wiring it into the brake system does not reduce the stop lamp output or otherwise affect the operation or the effectiveness of the stop lamp system.; You should also ensure that your product is acceptable under State an local laws as well. Because there are no Federal requirements for your product, each State may regulate it as it deems proper.; I am enclosing the samples that you enclosed, and hope that we hav answered your questions.; Sincerely, Erika Z. Jones, Chief Counsel |

WOOD -- NHTSA ROBERT KNAUFF; REDBOOK A33; FMVSS 108; LETTER DATED 06/08/89 FROM ROBERT J. KNAUFF -- APPLIED RESEARCH AND DESIGN INC TO KATHLEEN DEMETER -- DOT; LETTER DATED 12/07/87 FROM RICHARD H. SCHULTZ -- AMERICAN PULSE LIGHTS TO ROBERT J. KNAUFF TEXT: Dear Mr. Knauff: This is an evaluation of your school bus rear warning lamp demonstration with a pop-flash option. I initially expected that we would have a problem with high intensity flash washing out the red lens and appearing white. Technically this is what happens and if you concentrate on it, the flash can appear white. The flash duration however was so brief and when used in concert with red in the cycle did not appear white to me. That should clear one obstacle, as white is prohibited in this type of lamp. Dual day/night intensity should not be necessary as long as you stick with red lamps. You should also not have to restrict the pop to less than every flash, but in any case you will have to locate the discharge bulb so that the parabolic reflector and lens of the host lamp project the energy at very nearly about the H-Y point. Any large amount that occurs down at a level so as to be observed by a passenger car operator less than, let us approximate, 200 feet away would probably be objectionable to some, depending upon a number of factors that I need not go into at this point. Generally, we have a basic concept that a signal is either required or not permitted. This keeps messages clear between vehicle operators. In this case however, I believe that we can consider this option since it is only an appendage modification of an existing warning system. When you clear this modification with the National Highway Traffic Safety Administration compliance office and with the Minnesota Department of Education student transportation office, we would need to have a look at the finished product and your test da ta for purposes of commissioner's authorization or commissioner's approval certification depending upon the marketing approach that is possible and that you wish to take.

ID: nht89-3.24OpenTYPE: INTERPRETATION-NHTSA DATE: 10/31/89 FROM: STEPHEN P. WOOD -- NHTSA ACTING CHIEF COUNSEL TO: MARK F. HOLMES TITLE: NONE ATTACHMT: LETTER DATED 09/28/89 FROM MARK F. HOLMES TO STEVE WOOD -- NHTSA; OCC 3980; LETTER DATED 09/28/89 FROM MARK F. HOLMES TO STEVE WOOD -- NHTSA TEXT: Dear Mr. Holmes: This is in reply to your letter of September 28, 1989, with respect to two lighting devices known as the Strobalarm and the Spotlight Alarm. You are interested in selling these devices in the aftermarket, and have asked whether they would be in violatio n of any of the standards and regulations of this agency. These devices are "designed to be used only when a vehicle is parked or broken down." As we understand your letter and the materials you enclosed, both devices can be incorporated into existing alarm systems, to indicate when an attempted theft is in pro gress. The "locator" feature of the devices allows activation from a distance of 400 feet, enabling an approaching owner to easily identify his vehicle. With the use of a pink colored lens, the Strobalarm is intended to serve as an "emergency distress flare." You have enclosed two color renderings of these devices, titled "Interior/Strobe Alarm Light," and "Alarm Strobe Light Collision Avoidance Light." The Federal law and regulation that must be considered to answer your question are the National Traffic and Motor Vehicle Safety Act (Title 15, United States Code, Sections 1381 and following), and Federal Motor Vehicle Safety Standard No. 108 Lamps, Ref lective Devices and Associated Equipment (Title 49, Code of Federal Regulations, Section 571.108), and Standard No. 111 Rearview Mirrors (49 CFR 571.111). Under Section 1397(a)(2)(A) of the Act, a manufacturer, distributor, dealer, or motor vehicle repa ir business may not render inoperative, in whole or in part, any item of equipment installed in accordance with a Federal motor vehicle safety standard. You will note that this prohibition does not extend to the vehicle owner. Thus, the question to be addressed is whether the installation of either device by a manufacturer, distributor, dealer, or motor vehicle repair business would affect the performance of required safety equipment. The "Interior Strobe/Alarm Light" appears intended as a "dome" light, mounted centrally on the headliner above the passenger seats. In this position it has the potential to affect the field of view of the inside rear view
mirror required by Standard No. 111, as prescribed by paragraph S5.1.1 (copy enclosed). If the field of view is not met, an outside rearview mirror must be provided on the passenger side. You have not provided the dimensions of this device, and we are unable to advise you further. Other than this cautionary note, the "Interior Strobe/Alarm Light" does not appear affected by the laws and regulations of this agency. It would, however, be subject to state and local laws where it is sold and used. We a re unable to advise you on these, and suggest you contact the American Association of Motor Vehicle Administrators (AAMVA) for an opinion. Its address is 4600 Wilson Boulevard, Arlington, VA 22203. The "Alarm Strobe Light Collision Avoidance Light" raises another consideration. The collision avoidance portion of the lamp appears intended to serve as a center highmounted stop lamp. Under paragraph S5.4 of Standard No. 108, the center lamp may not b e combined with any other lamp or reflective device. Thus, removal of an original equipment center lamp and substitution of your device by a person other than the vehicle owner would be regarded as partially rendering inoperative the original safety equ ipment, even if your device complied with all other requirements for the center lamp. The center lamp has been required on all passenger cars manufactured on or after September 1, 1985. The restriction does not apply, of course, to installation on passenger cars manufactured before September 1, 1985, or other types of motor vehicles regardless of date of manufacture. Consideration must still be given, however, to continued compliance w ith Standard No. 111, and to whether any state specifications exist covering aftermarket center stop lamps. Again, the AAMVA may be able to help you. I hope that this information is useful to you. Sincerely, |

ID: aiam4354OpenMr. Mark Roberts, 40 East Stillforest, Houston, Texas 77024; Mr. Mark Roberts 40 East Stillforest Houston Texas 77024; Dear Mr. Roberts: This is in reply to your letter of June 9, 1987, with respect to a aftermarket motorcycle lamp that you wish to produce. You refer to the lamp as a 'motorcycle safety light' that would supplement other motorcycle lighting and 'would be a rear facing or all direction light with an amber colored lens that would flash'. You have asked if there are any restrictions or guidelines for such a lamp.; Your letter does not indicate the size, flash rate, or intensity of th light, nor whether you intend it so be installed by motorcycle dealers prior to the first sale, or available only for installation on motorcycles already in use. However, I can give you some general guidelines.; Federal Motor Vehicle Safety Standard No. 108, *Lamp, Reflectiv Devices, and Associated Equipment* contains the requirements that apply to motorcycles and must be met at the time of sale and delivery to their first owner. Generally, except as provided in the standard (*e.g* motorcycle headlamp modulating devices) all lamps must be steady burning in use. Your lamp, however, would flash, and therefore appears precluded as an item of original equipment. Further, vehicle equipment must not impair the effectiveness of lighting equipment required by the standard. Although in the absence of specifications of your lamp we cannot say whether it would impair the effectiveness of required motorcycle lighting equipment, we note that an(sic) rearward facing amber flashing lamp could create confusion with a rearward facing amber turn signal lamp.; As an aftermarket device intended for vehicles in use, your lamp i subject only to the Federal restriction that its installation by a dealer, distributor, or motor vehicle repair business shall not render inoperative in whole or in part other required lighting equipment. Should your device place an excessive drain on a motorcycle battery affecting the operability of other lighting equipment it could be viewed as violative of the Federal restriction. However, even if this question is answered in the negative, the question of the acceptability of the supplemental lamp is determined by the laws of the State in which the device is sold or used. We are unable to advise you on these laws, and suggest that you write American Association of Motor Vehicle Administrators, 1301 Connecticut Ave., N.W., Washington, D.C. 20016, for further information.; Sincerely, Erika Z. Jones, Chief Counsel |

STARDOR INTERNATIONAL PRIVATE LTD TO: TAYLOR VINSON -- NHTSA TITLE: REAR ENDER STOP LAMP ATTACHMT: ATTACHED TO LETTER DATED 09/29/87 FROM ERIKA Z. JONES -- NHTSA TO PETER MCINTOSH, REDBOOK A31, STANDARD 108; LETTER DATED 02/24/87 (EST) FROM ERIKA Z. JONES TO HAL MCNAMARA TEXT: Dear Mr Vinson, Mr Kumbar of the A.A.M.V.A. suggested I write to you & inform you of our wishes to obtain approval for the marketing of our Rear Ender brake light. This product was introduced into Australia in 1986 with great success and is now used by many corporations, government bodies & sporting groups to promote their product and incorporate a great safety device into their vehicles. With the statistics fr om the U.S.A. illustrating the reduction in rear end accidents by over 50% with the installation of a mid mounted brake light, acceptance of this concept was incredible with our promotional factor assisting to promote their use. Due to the acceptance and the interest shown we decided to try and export the product to the U.S.A. where the market is so much larger and where so many millions of cars still lack this safety system. On showing the product to a number of interested parties in the U.S.A. it is evident that this concept should receive much the same acceptance. Apart from the promotional angle main selling feature to most end users is the big advantages offered in safety. Our aim is mainly to introduce them to corporations for use in their own vehicles, used car sales for their stock and sporting groups for fund raising (support their team with endorsement on lights). Eventually we hope to introduce them onto the reta il market. With all new cars being factory fitted we do not see a market in this area, with the exception of 2wd vehicles and vans. The size of the lens is 10" x 2 1/2" offers excellent visibility and the most important feature of the lens is the fact that the message dissapears when the brake light is illuminated, thus not interfering with the initial design characteristic requir ement of the light. This factor has gained acceptance by the police departments in Australia and has encouraged a number of insurance companies to offer bonuses to their clients utilizing the mid mounted lights, e.g. no loss of no claim in the event of a rear end collision. The light has also been used by police and county vehicles to promote community messages such as "BUCKLE UP!", "SAY NOT TO DRUGS!" etc. Please find enclosed a copy of our brochure and I trust this information will be of assistance to you in evaluating our product.

ID: aiam4073OpenE. Timothy Pawl, P.E., President, Pawl Inventioneering Corporation, P.O. Box 5425, West Bloomfield, MI 48033; E. Timothy Pawl P.E. President Pawl Inventioneering Corporation P.O. Box 5425 West Bloomfield MI 48033; Dear Mr. Pawl: This is in response to your letter of November 29, 1985, to the forme Chief Counsel of this agency, Jeffrey R. Miller, asking for an interpretation of Motor Vehicle Safety Standard No. 108.; Your letter is vague as to the precise function of your 'safet related' lighting device, and whether you wish to offer it as original equipment or equipment intended for installation after the sale of a vehicle to its first purchaser for purposes other than resale. If the latter, then its legality is determinable solely under the laws of each State in which it will be used.; If you intend it as original equipment, on a vehicle at the time of it initial sale, then its legality would be determinable under Standard No. 108. As a general rule, section S4.1.3 prohibits the installation of any device that would impair the effectiveness of lighting equipment required by the standard. You have informed us that your device, which consists of 'amber LED's' in the 'rear package tray,' is inoperative during application of the service brakes, thus, it does not appear that it would impair the effectiveness of the center high-mounted stop lamp.; You have also stated that it is located 'in relative proximity' to th center stop lamp but is not combined with it, and you have asked if this meets the intent of S4.4.1 regarding equipment combinations. This section forbids the combination of the center stop lamp with any other lamp or reflective device. Since your device is physically separate from the center lamp, S4.4.1 would not appear to prohibit your device.; You have also stated that when viewed from the rear, 'the pattern o illuminated LED's may change, possibly giving the illusion of flashing,' and you ask for a definition of 'flashing' as described in section S4.6(c). This section has been renumbered S4.5.11, and subsection (c) permits an exception to the general rule that lamps in use must be steady-burning, permitting headlamps and side marker lamps to 'flash' for signalling purposes. The definition of flash is that contained in S3, a cycle of activation and deactivation by automatic means, and this definition does not specify frequency or other characteristics. To us, the important question is whether your device complies with section S4.5.11(e) which requires all lamps (other than those specifically excepted) to be steady-burning in use. A lamp that changes patterns may not flash, but it cannot be viewed as steady-burning either.; Finally, you state that 'section S4.3 states that no function othe than red reflex reflectors shall be combined with CHMSL or rear turn signal lamps' and ask whether amber or any other color 'may be used in proximity' since it is not used in combination. We believe you must be referring to section S4.4.1 which states that 'no clearance lamp may be combined optically with any taillamp or identification lamp, and no high-mounted stop lamp shall be combined with any other lamp or reflective device.' As we do not know the intended functions of your LED device, I can offer only general comments. Although red is the required color for all rear lighting devices except backup and license plate lamps, amber is permitted as an optional color for rear turn signals, furthermore, amber is generally accepted as indicating the need for caution. Thus, amber is not a lens color whose presence on rear lighting devices would *per se* impair effectiveness. The use of other colors for lighting devices on the rear of vehicles could lead to confusion, and be viewed as impairing the effectiveness of required lighting equipment.; Sincerely, Erika Z. Jones, Chief Counsel |

ID: nht87-3.31OpenTYPE: INTERPRETATION-NHTSA DATE: 11/19/87 FROM: AUTHOR UNAVAILABLE; Erika Z. Jones; NHTSA TO: Roger M. Cox -- R & R Lighting, Inc. TITLE: FMVSS INTERPRETATION ATTACHMT: 8/11/88 letter from Erika Z. Jones to J. Mike Callahan (A32; Std. 108); 4/14/87 letter from J. Mike Callahan to Taylor Vinson (occ 409); 9/3/87 letter from Erika Z. Jones to David M. Romansky TEXT: Mr. Roger M. Cox R & R Lighting, Inc. Route 1, Box 190 Gadsden, AL 35901 Dear Mr. Cox: This is in reply to your letter of July 8, 1987, with respect to whether a lighting product you intend to market is "in violation of any federal regulation when mounted on a motor vehicle." You describe your product as a "lighted decal" which can be mounted in the rear window of any car or pick-up truck, and the photographs you enclosed show it mounted in the center of the rear window of a pre-1980 model Seville. The decal will be wired int o the brake system and when activated by the brake "only the letters in the decal will be lighted." You state further that although the letters will appear red to an observer this product is not designed nor will it be marketed as a brake light or a tail light. In our opinion, your product may or may not be in violation of Federal requirements depending upon the following uses. The product does not appear to be intended as a substitute for the center highmounted stop lamp that has been standard equipment on pas senger cars manufactured on or after September 1, 1985. Indeed, it could not be so used unless it met all requirements for such a lamp. The principal requirements are that such lamps have a minimum of 4 1/2 square inches of illuminated lens area, that it meet specified photometrics at 13 test points, ad that it produce a signal visible from 45 degrees from the right to the left and from five degrees up to five degrees down. If your device does not meet these requirements, removal of the lamp and replace ment with your device would violate a prohibition of the National Traffic and Motor Vehicle Safety Act against rendering inoperative equipment installed in accordance with a Federal motor vehicle safety standard, in this case Safety Standard No. 108, Lam ps, Reflective Devices, and Associated Equipment. However, a dealer could install it on a new pick-up truck, or to one side of the center lamp in a new passenger car before their initial sale, provided the device did not impair the effectiveness of the r ear lighting equipment required by Standard No. 108, and the device could be installed on some vehicles in use (cars built before September 1, 1984, and any pick-up) provided that it did not render inoperative in whole or in part other required rear ligh ting equipment. By this we mean that the device appears allowable for these vehicles under Federal law provided that wiring it into the brake system does not reduce the stop lamp output or otherwise affect the operation or the effectiveness of the stop lamp system. You should also ensure that your product is acceptable under State and local laws as well. Because there are no Federal requirements for your product, each State may regulate it as it deems proper. I am enclosing the samples that you enclosed, and hope that we have answered your questions. Sincerely, Erika Z. Jones Chief Counsel Enclosure R & R Lighting, Incorporated Route 1, Box 190 Gadsden, Alabama 35901 July 8, 1987 Office of Chief Counsel National Highway Traffic Safety Administration 400 7th Street, S.W. Washington, D. C. 20590 Attention: Ms. Erika Jones Dear Mrs. Jones: I am in the final planning stage before marketing/manufacturing a new product. After having exhausted all efforts at state and national levels, I talked with Mr. Brooks in the Office of Vehicle Safety Compliance. It was Mr. Brooks' opinion that we are no t in violation of any federal laps, but he suggested I correspond with you to get an appropriate legal opinion as to whether my product in violation of any federal regulation when mounted on a motor vehicle. My product. the "#1-American Team Light", is a lighted decal. It is designed to be mounted in the rear window. My product can be mounted onany car or pick-up truck. It will be wired into the brake system and when activated by the brake, only the letters in the decal will be lighted. The letters will appear the same color as automobile manufacturers use in brake lights and tail lights; however, this product is not designed nor will it be marketed as a brake light or tail light. We have targeted the sport s enthusiast at high school and college level as our market group. We also feel we have a smaller market at local and state levels with a lighted decal that reads "Police" and "State Trooper". In order to effectively market my product at its peak season, which would be September, time is of the essence. I have enclosed a sample lens and photographs. Please review my information and sample and let me hear from you at your earliest convenience. If further information is needed, please call me collect at (205) 442-1642 or (205) 442-8436. Very truly yours, R & R LIGHTING INCORPORATED Roger M. Cox RMC/lc Enclosures |
