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.

Mr. Ken Hanna
Lectric Limited, Inc.
7322 S. Archer Road
Justice, Illinois 60458

Dear Mr. Hanna:

This responds to your letter of July 8, 1991, to Richard Van Iderstine of this agency. You asked whether a proposed manufacturing and marketing scheme would be in violation of any NHTSA regulations.

You intend to petition for rulemaking to amend Standard No. l08 to reinstate SAE Standard J579a as an optional standard for sealed beam headlamps. These lamps would be used on "antique cars." Until SAE J579a is reinstated, you would like to manufacture headlamps to conform to SAE J579c, the current specification for sealed beam headlamps that is incorporated into Standard No. 108. However, you do not wish to mark the lenses with the identification nomenclature that SAE J579c requires (presumably because it was lacking from the J579a headlamps with which the antique cars were originally equipped). You ask if you may market these lamps with identification on the package stating that they are "for display purposes only and not approved for highway use."

Your letter clearly indicates that the purpose of manufacturing the sealed beam headlamps is for their installation on motor vehicles, albeit old ones, and not for "display purposes only." The headlamps are motor vehicle equipment, and must comply with all applicable Federal motor vehicle safety standards, in this instance, SAE J579c. Partial compliance with the requirements is not permissible, and the lenses of headlamps manufactured to conform with SAE J579c must be marked as that standard requires. Thus, your suggested manufacturing and marketing scheme would not conform to Standard No. l08, and, if pursued, it would be a violation of the National Traffic and Motor Vehicle Safety Act.

The manufacture and sale of noncomplying motor vehicle equipment is a violation of the for which a civil penalty of up to $1,000 per violation may be imposed, up to a total of $800,000 for any related series of violations. In addition, as the manufacturer of the equipment, Lectric Limited must certify them as meeting all applicable Federal motor vehicle safety standards, and similar penalties may be imposed for certification that is false and misleading in a material respect. Finally, the manufacturer of nonconforming equipment is required to notify and remedy in accordance with the requirements of the Act.

Because SAE J579a and 579c headlamps are identical in external appearance except for lens marking, we do not believe that authenticity of the appearance of older vehicles will be affected to any discernable degree by requiring that their lenses be marked as the contemporary standard requires.

Sincerely,

Paul Jackson Rice Chief Counsel

TITLE: Petition for Rulemaking - FMVSS-108 Turn Signal Installation Requirements

ATTACHMT: Attached to letter dated 10/5/92 from Paul Jackson Rice to J. W. Lawrence (A-40; Std. 108)

TEXT:

The Administration established a new requirement for FMVSS-108 turn signals in Federal Register Vol. 56, No. 239, pp 64733 dated December 12, 1991 constituting an act of rulemaking without opportunity for comment and therefore in violation of 49 CFR Part 553. Volvo GM Heavy Truck Corporation respectfully petitions for the revocation of the "Figure 2" requirements published in the December 12, 1991 Register and restore the Standard to its prior status as amended May 15, 1990 in FR 55, No. 94.

This petition is filed in accordance with the requirements of 49 CFR Part 552, by Volvo GM Heavy Truck Corporation of 7900 National Service Rd., Greensboro, N. C. 27409. Volvo GM Heavy Truck Corporation manufacturers heavy duty trucks.

TECHNICAL DISCUSSION SUPPORTING THE PETITION

1. Docket 88-17 Notice 2 (FR 55, No. 94; May 15, 1990) upgraded the safety standard's SAE referenced requirements from "J588e September 1970" to "J1395, April 1985". The substantive portion of this change in FMVSS-108 is an increase in the lens luminous area from 8 sq. inches to 12 sq. inches.

SAE J1395, April 1985 was therefore incorporated as-is into 49 CFR Part 571.108 applicable to both front and rear turn signal lamps for vehicles over 80 inches wide.

2. "SAE J1395, April 1985" Installation Requirements are as follows:

"Signals from lamps on both sides of the vehicle shall be visible through a horizontal angle from 45 deg. to the left for the left lamp to 45 deg. to the right for the right lamp." (emphasis added)

3. Federal Register notice Vol. 56, No. 239, December 12, 1991 contains technically inaccurate information upon which the Administration has presumably based its interpretation and resulting rulemaking. The FR notice states in part as follows:

"Thus, the turn signals on both sides of the vehicle must be simultaneously visible through a horizontal angle from 45 degrees originating at the left lamp, to the left to 45 degrees to the right originating at the right lamp measured at a radius of 3 meters." (emphasis added) The requirement for "simultaneously visible" does not appear in SAE J585e,

SAE J1395 Apr. 85, SAE J1398 May 85 or in the May 1990 amendment to FMVSS-108.

The Administration should also be advised that the 3 meter requirement in SAE J1395 is for photometric measurement and has no connection to the 45 installation visibility which is the ability to observe 13cm2 (2 sq. inches) of outer lens surface at the 450 viewing angle.

4. FMVSS-108 Table I for vehicles over 80 inches wide requires 2 red or amber and 2 amber turn signal lamps. Table II "location of required equipment" for Truck, Bus and MPV over 80 inches wide does not require the turn signals be located on the rear except for trailers.

Turn signals are intended to signal pending maneuvers not mark the end of the vehicles.

In summary we wish to reaffirm that our petition is necessary to correct an unfortunate circumstance created by an inaccurate reference which has now become a requirement.

TITLE: 1975 MONARCH REAR TAILLAMP PART NO. (2)(A)(2) - IP2R(2)S(3)T75CT

ATTACHMT: ATTACHES TO A LETTER DATED 8/18/75 FROM JAMES C. SCHULTZ -- NHTSA CHIEF COUNSEL TO NANCY KOLODNY -- FORD MOTOR'S GENERAL COUNSEL; N40 30(ZTV)

TEXT: We are writing to seek the express confirmation of the National Highway Traffic Safety Administration (NHTSA) of the preemptive effect of Federal Motor Vehicle Safety Standard 108, 49 CFR 571.108 ("Standard 108") on passenger car lighting, as was provided by NHTSA in Motorcycle Industry Council, Inc. v. Younger, No. Civ. S74-126 (D.C.E.D. Cal., Sept. 24, 1974).

This request is being made so that we may respond to the attached correspondence (Attachment I) from Mr. Warren M. Heath, Commander, California Highway Patrol, concerning compliance with Section 25950 * of the California Vehicle Code by the 1975 Monarch rear taillamps. Mr. Heath's letters of April 8 and May 25 contend that the amber lens applied over a red lens on one of the Monarch taillamp compartments violates that provision of the California Vehicle Code Section 25950 which does not permit a taillamp to be amber when unlighted. On this basis, Mr. Heath has stated that similarly equipped 1976 model year Monarchs will not be eligible for registration in California.

* Section 25950 provides in pertinent part: "(b) All lamps and reflectors visible from the rear of a vehicle shall be red, except that stop lamps, turn signal lamps and front side-marker lamps required by Section 25100 may show amber to the rear.

This section applies to the color of a lamp whether lighted or unlighted, and to any reflector exhibiting or reflecting perceptible light of 0.05 candlepower or more per foot - candle of incident illumination, except that taillamps, stop lamps and turn signal lamps visible to the rear may be white when unlighted."

We believe the provisions of Section 25950 are preempted by Standard 108, and that pursuant to Section 103(d) of the National Traffic and Motor Vehicle Safety Act (15 USC 1392(d)), California is precluded from the enforcement of any nonidentical standard.

As the NHTSA has confirmed on several occasions, the Standard's lighting requirements are intended to be comprehensive and exclusive, and leave no room for differing state standards. The statement of the Administrator cited by the Court in the Motorcycle Industry Council judgment is particularly pertinent here where California seeks to enforce a differing standard for the precise function (i.e., taillamp color) covered by Standard 108. (Letter from James B. Gregory, Administrator NHTSA, to W. Pudinski, Commissioner, Dept. of Highway Patrol, dated Nov. 8, 1973, N40-30 (RBD).)

Compliance of the Monarch rear lamps with the requirements of Standard 108 has been confirmed by tests conducted at Ford. (Attachment II) Therefore, we seek an opinion on the issue of preemption with respect to the differing California requirements of Section 25950.

For your assistance, we are enclosing color photos of the Monarch and Monarch Ghia rear lamps which demonstrate their appearance when lighted and unlighted. (Attachment III) Photo #1 is of the Monarch rear lamp unlighted. Photo #2 shows the taillamp (3 exterior red compartments) lighted. Photos #3 and #4 are of the Monarch Ghia.

If you have any questions on this matter, please so inform me. I may be reached by telephone at (313) 337-6462. We hope to receive a response at your earliest convenience.

Dear Mr. Quinn: This is in reply to your letter of May 5 on behalf of your client Le Ross. Mr. Ross has developed a motor vehicle deceleration warning system that, as described by you, activates two amber lights on the rear of a vehicle. Your letter indicate that these lamps would be incorporated into a vehicle back-up lamp system and that Mr. Ross envisions his system as an aftermarket accessory item rather than as new vehicle original equipment. You state your understanding that Motor Vehicle Safety Standard No. 108 would not preclude marketing the system as an aftermarket accessory, and that back-up lamps are required to be white in color. You ask our advice whether Standard No. 108 prohibits amber lamps in the back-up lighting system and, if so, whether a proposal for amendment of the Standard to allow the system would be feasible.; Standard No. 108 would in certain instances preclude the aftermarke sale of an amber deceleration warning system incorporated into a back-up lamp system. Standard No. 108 as of January 1, 1972, does cover certain aftermarket equipment items, and in some instances would preclude the sale of a back-up light system with amber lamps. Lighting equipment manufactured on or after that date as replacement for similar equipment on vehicles manufactured on or after January 1, 1972, must meet Standard No. 108 which, as you have noted, requires that the color of the back-up lamps be white. Federal law would not preclude sale of this system for use on motor vehicles manufactured before January 1, 1972, or purchase of an amber system by the owner of a vehicle manufactured after that date if he wished to change over from a white to amber system. As a practical matter, however, I believe That(sic) virtually every State has a requirement that back-up lamps be white, and that a back-up light with amber bulbs or lenses would be forbidden. Standard No. 108 would not preclude sale of the Ross System as a separate lighting device. I do not know what position the States would take on such a matter.; Our research contracts on deceleration warning system indicate tha further development and testing under field conditions is necessary before specific proposals can be made by NHTSA. Therefore, I do not think action on a proposal by Mr. Ross would be feasible at this time, though we would welcome his comments to our Docket 69-19 as a comment to be considered in future rulemaking on this subject.; Yours truly, Richard B. Dyson, Assistant Chief Counsel

Dear Mr. Moore: This is in reply to your letter of December 27, 1976, asking severa questions about Federal Motor Vehicle Safety Standard No. 108. You referenced my letter of October 7, 1976 to Wesbar Corporation, and my views about the prohibition against the optical combination of lamps (S4.4.1).; It is evident from your letter and others that our previou interpretations of the term 'optical combination' have been found to be ambiguous and lacking in the objective criteria that a Federal motor vehicle safety standard must provide. We have reviewed the matter, and now wish to modify our previous interpretation. In our view a lamp is 'optically combined' when the same light source (i.e. bulb) and the same lens area fulfill two or more functions (*e.g.* taillamp and stop lamp, clearance lamp and turn signal lamp). A dual filament bulb would be regarded as the 'same light source'. In determining conformance, the photometric requirements for clearance and taillamp functions, where two bulbs are located in a single compartment, must be met with only the bulb energized that is designed to perform the specific function. But the 15 candlepower maximum under Standard No. 108, however, would be determined with both the taillamp and clearance lamp bulb energized. Further, the lamp must be located to meet requirements for both clearance and taillamps. our re- interpretation means that the issue of light spill-over from one area of the lamp to another is irrelevant to conformance.; You have also asked whether the November 1975 amendments (S4.3.1.1.1 'permit clearance lights that are designed *for OEM application only* be allowed to have lower or no photometrics in this area but still be considered a combination clearance and sidemarker lamp' as the lamp otherwise complies with Standard No. 108.; The amendment in question was intended to cover clearance lamps only If a lamp is intended as a combination clearance and side marker lamp and does not meet the requirements for a clearance lamp because of the exemption provided by S4.3.1.1.1, it must nevertheless meet the requirements for side marker lamps. If it doesn't, a separate conforming side marker lamp must be provided.; Yours truly, Frank Berndt, Acting Chief Counsel

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.

Mr. Thomas C. Gravengood
Agap'e Plastics Inc.
Grand Rapids, MI 49504

Dear Mr. Gravengood:

This is in reply to your letter of April 3, l989, to this Office enclosing samples of plastic lenses. Your company manufactures "heated lights" which appear beneficial in melting snow that accumulates on them in the winter months. In your letter, you stated:

"All lights, lenses, and materials to assemble the heated safety lights have already been certified and passed the Motor Vehicle Safety Standard No. l08. We have been advised by the National Highway Traffic Safety Administration that there is no motor vehicle safety standard no. for heated lights. In order for us to do business at the O.E.M. level we require a letter of approval from you to us that we may pass on to our customers so they may start ordering and we may start producing."

We have no authority to "approve" or "disapprove" items of motor vehicle equipment. Under the National Traffic and Motor Vehicle Safety Act, an equipment manufacturer "approves" each of its own products that are subject to a Federal motor vehicle safety standard by certifying that it meets all applicable Federal motor vehicle safety standards, or (if it is a vehicle manufacturer), that the vehicle on which the lamp is installed, complies with the standards. However, we can advise you of the relationship of your product to Standard No. l08. This should prove helpful in dealings at the O.E.M. level.

There are two types of O.E.M. lighting equipment: lamps that are required by Standard No. l08, and supplementary lamps that do not come under its coverage. Although your product literature indicates that the highmounted heated taillamp supplements the original equipment lamp, it is not clear whether the heated signal lamp serves as the required signal lamp or is a supplement to the original equipment. Accordingly, this letter discusses how Standard No. l08 treats both original required and original supplemental lighting equipment.

If you are the manufacturer of original lighting equipment required by Standard No. 108, but not the manufacturer of the vehicle on which it is installed, the vehicle manufacturer, and not you, has the legal responsibility under the Act and Standard No. l08 of ensuring that the equipment complies with the standard, and of certifying that the vehicle meets all applicable Federal motor vehicle safety standards. As a practical matter, however, vehicle manufacturers generally insist that equipment manufacturers provide assurance that their products meet Federal standards, but the "certification" they may insist upon is not required by the Act. You are correct that there is no standard that applies to heated lamps as such. The Federal standard that applies is the one imposed by Standard No. l08 for the particular equipment item (taillamps or signal lamps in this instance).

If you are manufacturing a lamp as an original equipment supplement to required original lighting equipment, the burden remains on the vehicle manufacturer who installs it. The only restriction on a supplementary lamp that Standard No. l08 imposes is that it not impair the effectiveness of the required lighting equipment (paragraph S4.1.3). Your lamps "splice into" the wiring for the taillamps and "marker lamps", according to your product literature. Therefore, it is incumbent upon the vehicle manufacturer to ensure that this installation does not negatively affect the performance of the required taillamps and signal lamps, or otherwise impair its effectiveness. If the vehicle manufacturer determines that no impairment exists, then it may certify that its vehicles comply with all applicable Federal motor vehicle safety standards.

Observing that the product literature depicts the heated taillamp installed in the upper corners of a school bus body, we must also call attention to an additional provision of Standard No. l08. The location depicted is one that is frequently used for the clearance lamps required by Standard No. l08. Paragraph S4.4 of Standard No. l08 forbids the optical combination of clearance lamps and taillamps. Thus, your lamp cannot optically combine these two functions if it is to be used as new vehicle equipment.

Other enclosures to your letter indicate that at present the heated lamp is being installed on buses in use, that is to say, as non-original equipment. The requirements imposed by Standard No. l08 and the Act for aftermarket manufacturers of lighting equipment differ from those for original equipment. If the lamp you produce is intended to replace an original equipment certified lamp, it is considered replacement equipment. As a manufacturer of a replacement taillamp or signal lamp, the legal obligation to produce a complying equipment item falls squarely upon you, as does the certification responsibility. If the lamp is intended only to replace a supplemental lamp, you are not required to certify. However, there may be instances in which your lamp is interchangeable with original certified equipment, and even though you may not intend it as replaceable lighting equipment, you may encounter questions from state and federal authorities if it is not manufactured and certified in accordance with Standard No. 108.

Finally, you should be aware of your responsibilities under the Act in the event that your products do not comply with Standard No. l08, or incorporate a safety related defect (an example would be the inability of the lens to withstand the heat produced during the lamp's operation without warping or cracking). If you or this agency determine that a noncompliance or safety related defect occurs in any item of replacement equipment that you manufacture, you have the obligation to notify purchasers, and to remedy the problem through repair, repurchase, or replacement of the item. With respect to original equipment, this obligation falls upon the manufacturer of the vehicle on which it is installed.

If you have any further questions we shall be happy to answer them. We are returning your samples.

Sincerely,

Stephen P. Wood Assistant Chief Counsel for Rulemaking

Gainesville, FL 32601

Dear Mr. Martin:

Thank you for your fax of October 19, 1999, asking for information on "how I can apply for a financial exemption for a new manufacturer of 49cc Scooters." You relate that the manufacturer "meets all the CFR requirements," but is concerned that one of the lamp manufacturers does not label his product with a DOT symbol. You report, however, that "the light in testing meets the National Highway Traffic Safety Administration testing standards."

Mr. Vinson of this Office, with whom you spoke, recalls that the lamp in question is the headlamp for motor driven cycles. Paragraph S7.2(a) of Federal Motor Vehicle Safety Standard No. 108, Lamps, Reflective Devices and Associated Equipment, requires the lens of any headlamp used on a motor vehicle, including motor driven cycles, to be marked with the symbol DOT which shall constitute the certification required by 49 U.S.C. 30115. If the headlamp is not so marked, and if testing of the headlamp shows compliance with the motor driven cycle headlamp specifications of SAE J584 April 1964, that would afford a basis upon which its manufacturer could certify compliance. In that event, a temporary exemption would not be required. Please note that S7.9.5 requires that headlamps meeting SAE J584 must also have the word "motorcycle" permanently marked on the lens.

Our temporary exemption procedures are set forth in 49 CFR Part 555. Because of the statutory requirement that we afford the public an opportunity to comment on petitions for exemptions, the process from receipt of an acceptable petition to action on it requires three to four months. While you may submit it on behalf of the manufacturer, the manufacturer must sign the petition. If the manufacturer is located outside the United States, it must first designate an agent for service of process pursuant to 49 CFR 551.45.

A person who is not a manufacturer of a motor vehicle certified for sale in the United States may import a non-conforming motor vehicle for research or investigations pursuant to 49 CFR 591.5(j)(1) and (2)(i) after receiving written permission from the agency (49 CFR 591.6(f)(1)).

You may access our regulations at in Title 49 Code of Federal Regulations through website

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.
