Truck-Lite 50373 – 50 Series 72” 1-Plug Marker Clearance Wiring Harness | Fit 'N Forget M/C to Blunt Cut, 14 Gauge
The Truck-Lite 50373 (50 Series) Marker Clearance Wiring Harness is an OEM-grade, heavy-duty electrical assembly engineered to power individual clearance or marker lamps on commercial trucks, trailers, and specialized utility fleets. Spanning 72 inches (6 feet) in length, this streamlined 1-plug harness delivers clean, continuous electrical distribution to localized lighting stations, ensuring your vehicle remains fully visible and compliant with federal DOT highway lighting safety standards.
Fit 'N Forget Technology for Superior Weather Isolation
Commercial vehicle wiring is subjected to intense road debris, high-pressure trailer washes, and highly corrosive winter de-icing chemicals. The Truck-Lite 50373 handles these demanding conditions with proprietary Fit 'N Forget M/C (Marker/Clearance) molded plug technology. This advanced connector design forms an airtight, moisture-proof barrier directly against the light fixture, effectively eliminating the risk of pin corrosion, water pooling, and premature pin rot.
The opposite termination side is Blunt Cut, granting fleet technicians maximum installation flexibility to cleanly route, custom-splice, or hardwire the 2-conductor internal lines directly into a primary junction block, secondary wiring extension, or main trailer trunk line without requiring bulky intermediate connectors.
