Truck-Lite 50310 – 50 Series 336” 1-Plug Marker Clearance Wiring Harness | PL-10 to Blunt Cut, 14 Gauge
The Truck-Lite 50310 (50 Series) Marker Clearance Wiring Harness is a heavy-duty, long-reach electrical assembly designed to power individual clearance or marker lamps on extended commercial vehicles. Spanning an impressive 336 inches (28 feet) in length, this streamlined 1-plug harness provides continuous, clean power from a central power source all the way to its designated light station. Built with robust 14-gauge copper conductors, it is optimized to maintain electrical current integrity and prevent voltage drop across long distances.
Rugged Construction for Long-Frame Reliability
Longer wiring runs face increased exposure to environmental elements, rubbing, and vibration along the vehicle frame. The Truck-Lite 50310 addresses these challenges with a robust, factory-molded round PVC outer jacket that seals the internal copper lines from road spray, moisture, chemical washes, and winter de-icing salts. It features a premium, molded PL-10 plug interface on one end, delivering a weatherproof seal directly to your standard marker lamp. The opposite end is Blunt Cut, giving fleet technicians maximum installation flexibility to custom-splice, hardwire, or pin the harness directly into a central junction block or main wiring trunk line without requiring unsafe intermediate splices.
