Truck-Lite 50300 – 50 Series 36” 3-Plug Identification Light Bar Wiring Harness | PL-10 to Blunt Cut, 14 Gauge

The Truck-Lite 50300 (50 Series) Identification Wiring Harness is a commercial-grade, heavy-duty electrical assembly engineered specifically for rear header or ID light bar systems on trucks, trailers, and commercial vans. Measuring 36 inches in length, this specialized 3-plug harness provides simultaneous, clean power to the required trio of identification lamps, ensuring your vehicle remains fully visible and compliant with federal lighting standards. Constructed with thick 14-gauge conductors, it offers superior physical durability and minimal voltage drop across the circuit.

Heavy-Duty Design for Fleet Longevity

Built to endure the punishing environments of long-haul trucking, the Truck-Lite 50300 features a robust, factory-molded construction that protects internal copper wiring from moisture, dust, and corrosive de-icing salts. It is outfitted with a premium PL-10 molded plug connector configuration on one end to deliver a secure, weatherproof seal directly to your ID light assembly. The opposite end is Blunt Cut, giving fleet technicians maximum installation flexibility to custom-splice, hardwire, or pin the harness into a central junction block or main wiring trunk line.
