Truck-Lite 50301 – 50 Series 288” 3-Plug Upper Identification Light Bar Wiring Harness | PL-10 to Blunt Cut, 14 Gauge
The Truck-Lite 50301 (50 Series) Identification Wiring Harness is an extra-long, commercial-grade electrical assembly designed specifically for rear headers, upper bodies, or ID light bar systems on large commercial trucks, trailers, and logistics fleets. Spanning an impressive 288 inches (24 feet) in length, this specialized 3-plug upper harness effortlessly reaches down extended frame lengths to provide simultaneous, clean power to a trio of identification lamps, keeping your vehicle 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 and external friction. The Truck-Lite 50301 handles these demands by utilizing thick, heavy-duty 14-gauge copper conductors wrapped in a rugged, protective round jacket. It is outfitted with a premium PL-10 molded connector plug layout on one end—engineered with specific center distances (6 in. / 15 in. / 15 in.) to deliver a tight, moisture-proof seal directly to your rear ID light assembly. The opposite side features a Blunt Cut termination, giving fleet technicians ultimate flexibility to hardwire, custom-splice, or pin the harness directly into a central junction box or main power line.
