Truck-Lite 50334 – 50 Series 324” 3-Plug Identification Light Bar Wiring Harness | PL-10 to Blunt Cut, 14 Gauge
The Truck-Lite 50334 (50 Series) Identification Wiring Harness is an extra-long, commercial-grade electrical assembly designed specifically for rear headers or upper ID light bar systems on large commercial trucks, semi-trailers, and logistics fleets. Spanning an impressive 324 inches (27 feet) in length, this specialized 3-plug harness effortlessly reaches across extended frame rails and up vehicle rooflines. It provides clean, simultaneous power to the required trio of identification lamps, keeping your fleet fully visible and compliant with federal DOT highway safety standards.
Heavy-Duty Extended Reach for Fleet Longevity
Longer wiring runs are highly susceptible to voltage drops, friction, and environmental wear. The Truck-Lite 50334 addresses these demands by utilizing thick, heavy-duty 14-gauge copper conductors wrapped in a rugged, protective round jacket. It features a premium PL-10 molded plug configuration on one side, delivering a moisture-proof, corrosion-resistant connection directly to your standard identification lamps. The opposite side is Blunt Cut, giving fleet technicians maximum installation flexibility to custom-splice, hardwire, or pin the harness directly into a local junction block or main trailer trunk line without requiring unsafe intermediate field splices.
