Dear Mr. Bethurum:
Your letter of December 14, 1990, to the "U.S. National Highway Safety Commission" for reply. Our agency, the National Highway Traffic Safety Administration, is the Federal agency responsible for establishing and enforcing the Federal motor vehicle safety standards.
Your client, Mr. E.D. Farnsworth, has asked about "when and how side lights adjacent to the main head lights came to be first used with head lights on automobiles." You have, in turn, asked to be apprised of the regulations which govern new headlamp designs for automobiles and other motor vehicles.
The Federal regulations that apply to motor vehicle headlamps are found in 49 C.F.R. 571.108, Federal Motor Vehicle Safety Standard No. l08, Lamps, Reflective Devices, and Associated Equipment. The current version of the CFR volume (Parts 400 to 999) containing that standard is updated to October 1, l990.
We are uncertain as to what you mean by "side lights adjacent to the main head lights". Standard No. l08 requires amber or white parking lamps on the front of passenger cars and other types of motor vehicles whose overall width is less than 80 inches, amber turn signal lamps, and amber front side marker lamps. Other types of lamps that are sometimes found on the front, and on the side at the front, are fog lamps and cornering lamps. They are not required by Standard No. l08, and are permissible as long as they do not impair the effectiveness of the lighting equipment required by the standard.
Standard No. l08, which has been in effect for passenger cars since January l, l969 (the mandatory requirement for a side marker lamp replaced the earlier provision giving manufacturers a choice of lamp or reflector effective January 1, l970), has always prescribed lamp location in general terms. Thus, parking lamps and headlamps are to be installed "at the front" and "as far apart as practicable" (Table IV of Standard No. l08). Similarly, turn signals are to be located "at or near the front" and "as far apart as practicable." Amber side marker lamps are to be on the side but placed "as far to the front as practicable." Because Standard No. l08 does not otherwise specify lamp location, we surmise that the head lamp and adjacent side lamp relationship to which you refer resulted from the choice of the vehicle manufacturer within the overall general parameters of the Federal specifications.
If you have further questions, we shall be pleased to answer them.
Sincerely,
Paul Jackson Rice Chief Counsel
