Truck-Lite 50308 – 50 Series 36” 4-Plug Lower Identification & License Plate Light Wiring Harness | PL-10 to Blunt Cut, 14 Gauge
The Truck-Lite 50308 (50 Series) Identification and License Plate Light Wiring Harness is an OEM-grade, heavy-duty electrical assembly engineered for lower mounting positions on commercial trucks, semi-trailers, and buses. Measuring a clean 36 inches (3 feet) in length, this specialized 2-conductor harness delivers simultaneous, clean electrical distribution to both your license plate illumination lamp and your lower identification/marker light bars, ensuring full DOT visibility and fleet regulatory compliance.
Heavy-Duty Construction for Lower-Chassis Reliability
Wiring mounted near the lower frame or bumper section faces constant exposure to road debris, mud, water spray, and aggressive winter de-icing chemicals. The Truck-Lite 50308 solves this problem by using a robust, factory-molded round PVC outer jacket that seals its internal copper lines away from environmental contaminants. This harness is outfitted with premium PL-10 molded plugs on one end—specifically spaced at center-to-center distances of 6 in. / 15 in. / 15 in. / 20 in. to line up with standard lower light assemblies. The opposite side features a Blunt Cut termination, giving fleet mechanics the absolute freedom to cleanly custom-splice, hardwire, or terminal-pin the harness directly into a local junction block or central trailer trunk line.
