Truck-Lite 51375 – 50 Series 3-Plug 116 in. Marker Clearance Jumper Wiring Harness (14 Gauge, Round Cable, 2 Position .180 Bullet & PL-10 to .180 Bullet Terminal)

Streamline your commercial trailer or heavy-duty fleet lighting system with the Truck-Lite 51375 50 Series Marker Clearance Jumper Wiring Harness. Spanning 116 inches (approx. 9.6 ft.), this multi-plug clearance harness is engineered to safely distribute power across multiple marker and clearance lamps on commercial vehicles, semi-trailers, and specialized vocational rigs.

Built to withstand grueling over-the-road environments and continuous exposure to the elements, the 51375 harness features extra-thick, ultra-durable 14-gauge (14 AWG) copper conductors. This heavy-duty 14 ga. wire construction minimizes electrical resistance, successfully preventing voltage drop across multiple light connections to keep your LED or incandescent lamps burning bright. The rugged round cable jacket shields the internal 2-conductor color-coded wiring (Brown and White) against pinches, abrasions, and road debris.

This OEM-quality harness delivers versatile integration with specific multi-terminal configurations. It features a 3-plug design layout with a center-to-center plug spacing configuration of 6 inches / 6 inches / 4 inches, making it perfectly optimized for clean modular runs. Equipped with specialized 2 Position .180 Bullet and PL-10 plug connections on one end, and standard .180 Bullet Terminals on the other, this harness provides a tight, moisture-proof seal that actively blocks out corrosive road salts, dust, and water to eliminate circuit failures caused by heavy vehicle vibration.
