The identification bar with red lights is designed to conform to applicable US FMVSS108 and Canadian CMVSS safety standards. This attractive black polycarbonate bar easily installs to any over 80 in vehicle or trailer. Highly visible for safety and security while traveling day or night and in all weather conditions. The air-tight seal prevents water leakage, extending the life of the light. The sturdy, black base mounts on 7-1/2 in centers. The two-wire design includes a 50 in lead wire and ground wire that easily mounts to any surface. The light bar contains three separate, replaceable clearance lights. Each light has a highly durable ABS housing sealed onto the acrylic lens that provides reflex function to eliminate the need for additional reflectors.
