DOT compliance means that the lighting meets section 108 requirements of the Federal Motor Vehicle Safety Standards (FMVSS 108). These standards regulate all automotive lighting, signaling, and reflective devices. The FMVSS are established and administered by the National Highway Traffic Safety Administration (NHTSA), an arm of the U.S. Department of Transportation (DOT) and an executive branch of the U.S. government.
Meeting FMVSS 108 standards means both designing and testing products meet performance and quality standards. All our trailer lights are tested by a DOT acknowledged test lab: Calcoast-ITL and certified as compliant with FMVSS 108 standards (i.e., photometric tests, lens area tests, visibility tests, color tests, and plastic optical material tests)
