Dear Mr. Bartlett: This is in reply to your letter of November 27, 1974, asking about th legality of rectangular headlamps, particularly with respect to the aftermarket.; Federal Motor Vehicle Safety Standard No. 108, *Lamps, Reflectiv Devices and Associated Equipment*, permits the use of a four-headlamp system with rectangular lenses of specified dimensions (approximately 4-1/4 by 6-1/2 inches), on vehicles manufactured between January 1, 1974, and August 31, 1976. The standard also permits manufacture of replacement headlamps for this system for sale in the aftermarket. The standard does not allow rectangular headlamps of other sizes, or a two-headlamp system, either as original equipment or for sale in the aftermarket.; I enclose a copy of that portion of Standard No. 108 covering th rectangular headlamps.; Yours truly, Richard B. Dyson, Acting Chief Counsel
