Federal Motor Vehicle Safety Standard 108

Federal Motor Vehicle Safety Standard 108 (FMVSS 108) regulates all automotive lighting, signalling and reflective devices in the United States. Like all other Federal Motor Vehicle Safety Standards, FMVSS 108 is administered by the United States Department of Transportation's National Highway Traffic Safety Administration.

Canada's analogous regulation is called Canada Motor Vehicle Safety Standard 108 (CMVSS 108), and is very similar to FMVSS 108. The primary differences are:

• CMVSS 108 requires daytime running lamps on all vehicles made since 1 January 1990, while FMVSS 108 permits but does not require DRLs
• CMVSS 108, through an adjunct called CMVSS 108.1, permits European headlamps, while FMVSS 108 prohibits them.

Both standards differ markedly from the UN (formerly "European") standards used in most other countries worldwide, not only in technical provisions, terminology, and requirements, but in format: each European standard deals with only one type of lighting device, while the single U.S. and Canadian standards regulate all lighting and reflective devices.
