Truck-Lite 50351 – 50 Series 720” 1-Plug Marker Clearance Wiring Harness | PL-10 to Blunt Cut, 14 Gauge
The Truck-Lite 50351 (50 Series) Marker Clearance Wiring Harness is a heavy-duty, ultra-long-reach electrical assembly designed to power individual clearance or marker lamps on maximum-length commercial vehicles, multi-axle trailers, and extended fleet setups. Spanning an impressive 720 inches (60 feet) in length, this streamlined 1-plug harness delivers continuous, clean power from a centralized front junction block all the way to its designated rear or upper lighting station. Built with premium 14-gauge copper conductors, it is engineered to maintain electrical current integrity and mitigate voltage drop across extreme distances.
Rugged Construction for Extreme-Length Reliability
Maximum-length wiring runs face severe environmental exposure, constant structural vibration, and potential frame-rail friction over their long spans. The Truck-Lite 50351 addresses these challenges with a robust, factory-molded round PVC outer jacket that completely seals the internal wiring from road spray, moisture, dirt, and corrosive winter de-icing chemicals. One side is outfitted with a premium PL-10 molded plug connector, establishing a secure, weatherproof fit directly to your marker lamp. The opposite termination side is Blunt Cut, granting fleet technicians maximum flexibility to cleanly route, custom-splice, or hardwire the internal conductors directly into a primary distribution panel or main trailer trunk line without requiring unsafe intermediate field splices.
