Dear Mr. Green: In his letter of June 16, 1977, our Mr. Driver, Director of the Offic of Crash Avoidance, commented that although the Federal motor vehicle lighting standard 'is generally in accordance with standards developed and published by the Society of Automotive Engineers, it does not specifically require sealed-beam headlamps.'; This should not be interpreted as an opinion that Federal Motor Vehicl Safety Standard No. 108 does not require sealed beam headlamps. While there is no such requirement *per se* in the text of the standard, Standard No. 108 incorporates by reference SAE Standard J579a *Sealed Beam Headlamp Units for Motor Vehicles*, August 1965, and SAE Standard J580a *Sealed Beam Headlamp*, June 1966. Compliance of headlamps with these standards is required, whether as original or replacement equipment.;
