TEXT: Thank you for your letter of May 24, 1968, to Mr. J. E. Leysath of this Bureau, concerning the testing of automotive flasher devices.

Motor Vehicle Safety Standard No. 108 specifies that turn signal flashers and vehicular hazard warning signal flashers conform to SAE Standards J590b and J945, respectively. These SAE standards, in turn, require that the test circuitry and test instrumentation conform to SAE Standard J823a. As you noted, the distribution of the 0.10+/-0.01 ohm series resistance in the standard test circuit (Figure 1 of J823a) is not specified in SAE Standard J823a. Therefore, your recommended distribution, namely, 0.025+/-0.005 ohms resistance between the power supply (positive terminal) and flasher input terminal, and 0.075+/-0.005 ohms resistance between the flasher output terminal and the flasher bulbs, would be permitted by SAE Standard J823a.

Flasher units having a ground terminal that is connected with the negative terminal of the power supply may be tested in the standard test circuit of SAE Standard J823a, provided the ground circuitry does not change the required resistance of 0.10+/-0.01 ohm looking into terminals A-B with the removable shunts in place (see note for Figure 1, SAE J823a).

The above-stated test provisions in no way except the flasher units from meeting all performance requirements specified in Standard No. 108, including those specified in basically referenced SAE Standards J590b, "Automotive Turn Signal Flashers," and J945, "Vehicular Hazard Warning Signal Flasher."

TEXT: Thank you for your letter of December 19, 1967, to the National Highway Safety Bureau, in which you request information governing vehicle width and safety glass installation requirements on the vehicles you manufacture.

Regarding your question on vehicle width, Safety Standard No. 108 relative to lamps, reflectors and associated equipment, for specified vehicles 80 or more inches wide overall, defines the term "overall width" as the nominal design dimension of the widest part of the vehicle, exclusive of signal lamps, marker lamps, outside rear view mirrors, flexible fender extensions and mud flaps, determined with doors and windows closed and the wheels in the straight ahead position. Therefore, if your vehicle measures less than the Safety Standard No. 108 requires, compliance is not required.

Your question regarding installation of safety glass as specified by Safety Standard No. 205, relative to Glazing Materials, can be answered by directing your attention to Standard No. 205. It specifies adherence by a multi-purpose Passenger Vehicle, a category into which your pick-up campers fall. A copy of the Federal Register, Volume 32, No. 23 and amendment to this regulation, Volume 32, No. 131, is enclosed for your information.

The application of Safety Standard No. 205 to pick-ups, is covered by the enclosed Federal Register, Volume 33, No. 59.

Thank you for your cooperation and response to the Federal Highway Administration request regarding the certification requirement.

The label sample and information as to its location that you have provided will be very useful to us, however, in accordance with Section 112 of the National Traffic and Motor Vehicle Safety Act of 1966, it would be appreciated if you would provide us with the serial indentification system in order that vehicles manufactured (completed) after January 1, 1968, can be identified.

Your interest in the safety program of the Bureau is appreciated.

TEXT: Thank you for your letter of May 2, 1968, which included additional information for certification under Public Law 89-563 and your coments.

You will note that Federal Motor Vehicle Safety Standard No. 108 does not restrict the height of the identification lamps from the roadway. You may find it suitable to mount these lights at a lower level than indicated in your illustrations.

With respect to the requirements of Standard No. 103, I must point out that this Bureau does not issue approvals on items of lighting equipment or on vehicle designs incorporating this equipment. Therefore, the above comments are for your information only and in no way relieve the vehicle manufacture from his responsibility for certifying that the assembled vehicle meets the requirements of the standard.

I am enclosing a copy of the National Traffic and Motor Vehicle Safety Act of 1966 which defines the vehicles to which it applies.

TEXT: Thank you for your letter of April 10, 1968, addressed to Mr. William H. Risteen, concerning the requirement for headlamp dimmer switches as specified in Federal Motor Vehicle Safety Standard No. 108.

Paragraph S3.4.1 of Standard No. 108 requires that a means for switching between lower and upper headlamp beams shall be provided in accordance with SAE Recommended Practice J564a or J565a. This general requirement is applicable to all vehicles, including motocycles, that are required, by Standard No. 106, to be equipped with lower and upper bean headlamps, even though SAE Recommended Practice J564a is addressed only to passenger cars.

Thank you for writing.

TEXT: Thank you for your letter of July 30, 1969, in which you request additional information in regard to certification requirements.

The statement in your letter to the effect that because detailed label requirements are now being prepared, you are not required to affix a certification label on your motorcycles currently being manufactured is not exactly correct. The "Certification Requirement Notice," published in the Federal Register, Volume 32, Number 215, dated November 4, 1967, a copy of which is enclosed, states that a certification label or tag should be affixed to each applicable motor vehicle if manufactured on or after January 1, 1968. In your case the only safety standard that currently involves motorcycles is Number 205, "Glazing Materials," pertaining to windshields. On January 1, 1969, another safety standard, Number 108, "Lamps, Reflecting Devices, and Associated Equipment," will involve motorcycles manufactured on or after that date.

For your immediate information, a copy of the Federal Motor Vehicle Safety Standards with Amendments is enclosed, with particular attention called to Table III, page MVSS 108-18 (1965) and Table IV, page MVSS 108-20 and 21 (1969).

In regard to your question as to whether you have to add the year of manufacture to your serial numbers, this is not a specific requirement, but would be an aid to clarifying the serial numbering system that identifies applicable vehicles as manufactured on or after January 1, 1968.

The study involving the possibility of specific changes to certification requirements is currently in the proposed rule making category and if changes do become finalized they will be published in the Federal Register.

Please furnish this office with the requirements shown in paragraph 3 in the enclosed Certification Requirement Notice at your earliest convenience.

I trust this information will be of assistance to you in regard to your inquiries.

TEXT: In your letter of December 6, 1967, you requested our comments on the applicability of SAE Standard J567, as sub-referenced in Motor Vehicle Safety Standard No. 108.

As mentioned in your letter, the intent of the reference to SAE J567 is to ensure that replacement bulbs are compatible with the standard bulb sockets. Therefore, any sealed, disposable type, bulb-lens unit, in which the bulb is not a replaceable component, need not comply with the requirements of SAE Standard J567. This provision in no way exempts these sealed units from the other requirements of Motor Vehicle Safety Standard No. 108.

TITLE: FMVSS INTERPRETATION

TEXT: In your letter of December 12, 1967, you questioned several requirements of Initial Motor Vehicle Safety Standard No. 108 as applied to fire trucks.

Paragraph S3.1.1.3, which permits the installation of additional equipment if it does not impair the effectiveness of the required equipment, will not prohibit the installation of rotary flashing lights on fire trucks. Therefore, a waiver of this clause is not necessary for fire trucks.

Paragraph S3.5 a revised by the latest amendment to Standard No. 108, and issued December 11, 1967, (copy enclosed), permits the flashing of steady-burning lamps for signalling purposes. Therefore, the flashing of side marker and clearance lamps on fire trucks to signify an emergency vehicle will not be prohibited by the requirements of this paragraph.

Standard No. 108 does not require that front identification lamps be located on the roof of the vehicle cab, but only that they be "as near as practicable to(Illegible Word) vertical centerlines." If, however, they are mounted on the upper body structure, "no part of the lamps or mountings may extend below the top of the vehicle's windshield." This mounting flexibility will permit a selective location of identification lamps and rotary warning lamps which will not cause the rotary lamps to blot out the identification lamps. Also to be considered is the effectiveness of the identification lamps when the vehicle is operated on the highway and without illumination of the rotary lamps. Therefore, fire trucks need not be excepted from the requirement for front identification lamps.

Rear identification lamps mounted on the edge of or under the rear step of a fire truck will meet the location requirements as specified in Standard No. 108. Adequate guards or protective shields are available and commonly used on lamps located in these positions. Therefore, fire trucks need not be excepted from the requirement for rear identification lamps.

If you have any further comments or questions on the requirements of Standard No. 108, I hope you will let us know.

TEXT: In your letter of December 18, 1967, to Mr. Lowell K. Bridwell, you describe the procedure initiated by you for identifying and marking light hit containers. You ask for our acknowledgement of the procedure. It is not clear from your letter, but we gather that you manufacture truck bodies and ship light kits in a separate box, either to accompany or separate from the truck bodies.

The so-called "lighting Standard," Standard 103 of the initial Federal Motor Vehicle Safety Standards, to entitled "Lamps, Reflective Devices, and Associated Equipment." The standard applies to multipurpose passenger vehicles, trucks, trailers and buses, that are 80 or more inches wide overall, except pole trailers and converter dollies. It is the manufacturer of the completed vehicle who must certify that the vehicle conforms to all applicable Federal motor vehicle safety standards, including Standard No. 103. Unless the manufacturer of the lighting equipment and the completed vehicle are the same, the manufacturer of lighting equipment is not required to certify that such equipment conforms to Standard No. 103. It would seem logical to expect that the manufacturer of the completed vehicle would require from the manufacturer of the lighting equipment some indication that the lighting equipment is in conformity, but that is a matter to be settled between the two persons involved. Thus, while we have no objection to the procedure described in your letter, we do wish to emphasize that it does not relieve the vehicle manufacturer of insuring compliance and certifying to such compliance where appropriate.

Thank you for your interest. If further information is needed, please feel free to contact this office.

TEXT: Thank you for your letter of April 5, 1968, (Reference 61.A218.A1115) addressed to Dr. William Haddon, Jr., concerning the location of clearance lamps on several styles of truck bodies manufactured by the Utility Body Company.

Rear clearance lamps mounted at the top corners of the sleeper cab of the vehicle in Figure 1 of the drawing attached to your letter would not be in conformance with the requirements of Federal Motor Vehicle Safety Standard No. 108. On this same vehicle, the required location of the front clearance lamps is at the top corners of the sleeper cab. The additional set of front clearance lamps on the truck cab would not be required or prohibited by Standard No. 103. Locations of rear clearance lamps on the vehicles shown in Figure 2 and Figure 3 of the drawing are in accordance with the requirements of Standard No. 108.

Our records do not indicate that we have furnished any evidence to the Utility Body Company regarding location of rear clearance lamps as shown in Figure 1. Under their letter of March 11, 1968, this company submitted to us a print of their drawing, which is identical to the drawing enclosed with your letter, and requested our comments on the proposed locations of their lighting equipment. The above information will be furnished to the Utility Body Company in reply to their March 11 letter and should serve as clarification of the requirements of Standard No. 108. This clarification also indicates that no conflict exists between the requirements of Standard No. 108 and the requirements of the California Vehicle Code with respect to location of your clearance lamps.

TEXT: Thank you for your telegram of May 3, 1968, concerning the use of tabular-type bulbs to back the requirements of Federal Motor Vehicle Safety Standard No. 108.

Paragraph S3.1 and Tables I and III of Standard No. 108, as amended (32 F.D. 13933, December 10, 1967), specify that certain lamp assemblies such as license plate lamps, backup lamps and tail lamps, shall conform to the basic SAE Standards for the lamp assemblies. These basic standards in turn refer to SAE Standard 7573 on bulbs and to SAE Standard 3567 on bulb sockets. This relationship between the basically referenced standards and subreferenced standards has been the subject of prior communications with the industry and appears to be in need of clarification.

The basically referenced SAE Standards also refer to SAE Standard J575, "Test for Motor Vehicle Lighting Devices and Components." Paragraph "C" of SAE Standard J575 states in part as follows: "Where special bulbs are specified, they should be submitted with the devices and the same or similar bulbs used in the tests and operated at their rated mean epherical candlepower." This provision of SAE Standard J575 permits the use of special bulbs, including tubular-type bulbs, which do not conform to the detailed requirements of Table I of SAE Standard J573. It also follows that the sockets for these special bulbs need not conform to SAE Standard J567. I must emphasize, however, that these provisions for special bulbs in no way except the lamp assemblies from testing all performance requirements specified in Standard No. 108, including those specified in the basically referenced SAE Standards and in subreferences SAE Standard J575.

In view of the several inquiries we have resolved on this particular(Illegible Word) of the requirements of Standard No. 108, we anticipate that an official interpretation, providing the clarification presented in this letter, will be published in the Federal Register in the near future.

Thank you for your continued interest in the Federal Motor Vehicle Safety Standards.
