Certification

It is the responsibility of a manufacturer of vehicles and/or vehicle lamps to certify that each motor vehicle and/or lamp is in full compliance with the minimum performance requirements of FMVSS 108. This is a self-certification process as opposed to the type approval process which is used in other lighting regulations such as UNECE Regulation 48. In order to show compliance to FMVSS 108, the lens of each original equipment and replacement headlamp, daytime running lamp (DRL) and certain conspicuity reflectors must be marked with the symbol “DOT.” This symbol may also be applied to compliant signal lighting devices, but is not mandatory.
