Work truck lighting requirements

Today, a nearly limitless variety of work trucks — with a multitude of bodies, equipment and accessories — are available. This means it can be challenging for upfitters (final-stage manufacturers and alterers) to properly meet all lighting requirements under Federal Motor Vehicle Safety Standard (FMVSS) 108: Lamps, Reflective Devices and Associated Equipment, and Canadian Motor Vehicle Safety Standard (CMVSS) 108: Lighting Systems and Reflective Devices.
