SUMMARY:

Our safety standard on lamps, reflective devices, and associated equipment specifies performance requirements intended to reduce the incidence of vehicle crashes by providing adequate illumination of the roadway and by enhancing motor vehicle conspicuity in daylight, darkness, and other conditions of reduced visibility. As a result of various safety initiatives and technological advances in vehicle lighting, numerous amendments to the regulatory text have left the standard unwieldy and unnecessarily complicated. In addition, the standard's provisions have been interpreted frequently by the agency over the past several decades in response to interpretation request letters. This document proposes to amend the standard by reorganizing the regulatory text so that it provides a more straight-forward and logical presentation of the applicable regulatory requirements, which includes the agency's interpretation of the existing requirements. This proposal would not impose any new substantive requirements on manufacturers.
