Truck-Lite 50302 – 50 Series 240” 5-Plug Upper Marker Clearance & ID Wiring Harness | PL-10 to Blunt Cut, 14 Gauge
The Truck-Lite 50302 (50 Series) Marker Clearance and Identification (ID) Wiring Harness is a heavy-duty, long-reach electrical assembly designed to simplify upper body lighting on commercial vehicles. Spanning 240 inches (20 feet) in length, this premium 5-plug harness seamlessly channels power across extended rooflines or upper headers to simultaneously run your vehicle's combination clearance marker lights and center identification light bars. Built with rugged 14-gauge copper conductors, this harness maintains strong current integrity and prevents voltage drops over a long distance.
Heavy-Duty Construction for Fleet Longevity
Upper trailer headers are continuously exposed to severe weather, wind resistance, and low-clearance branches. The Truck-Lite 50302 addresses these challenges by enclosing the wiring circuit inside a thick, factory-molded round PVC outer jacket. It features molded PL-10 pigtail plugs to deliver a moisture-proof, corrosion-resistant connection directly to your standard marker lamps. The opposite termination side is Blunt Cut, allowing fleet mechanics ultimate flexibility to cleanly route, splice, or hardwire the assembly directly into a primary junction box or central wiring subsystem.
