Rugged Construction for Demanding Road Conditions
Commercial fleet vehicles face constant exposure to severe weather, high-pressure trailer washes, and corrosive road grime. The Truck-Lite 50309 addresses these challenges with a robust, factory-molded round cable construction that completely seals the internal wiring from moisture, dirt, and winter de-icing salts. It features a premium, molded PL-10 connector interface with a standard 6/20-inch plug center distance, delivering a secure, weatherproof fit directly to your marker lamps. The opposite side is Blunt Cut, giving fleet technicians maximum installation flexibility to cleanly route, custom-splice, or hardwire the assembly directly into a primary junction block or main trailer trunk line.
