Abstract
This document amends the Federal motor vehicle safety standard on lighting to allow high intensity discharge (HID) light sources to be used in replaceable bulb headlamp systems, in addition to their presently allowed use in integral beam headlamp systems. Adoption of this amendment requires corresponding amendments to part 564, the regulation under which Docket No. 93-11 was established as a depository for replaceable light source information. However, if the life of the light source approaches that of the vehicle, as is the case with HIDs, interchangeability will no longer be so important. Therefore, NHTSA is adding Appendix B to part 564 which allows a manufacturer to submit fewer items of dimensional information if it can demonstrate that the rated laboratory life of its light source is not less than 2,000 hours.
