Truck-Lite 51409 – 50 Series 2-Plug 184 in. Marker Clearance Jumper Wiring Harness (14 Gauge, 2 Wires, 2 Position .180 Bullet to .180 Bullet Terminal)

Keep your commercial trailer and heavy-duty fleet running safely and fully compliant with the Truck-Lite 51409 50 Series Marker Clearance (M/C) Jumper Wiring Harness. Spanning an impressive 184 inches (approx. 15.3 ft.) in standard stocked length, this premium heavy-duty harness is engineered to route clean, uninterrupted electrical current across multiple marker and clearance lamp configurations on commercial vehicles, semi-trailers, body builders, and specialized vocational rigs.

Built to overcome the brutal over-the-road environments that commercial haulers face, the 51409 harness features extra-thick, ultra-durable 14-gauge (14 AWG) copper conductors. This heavy-duty 14 ga. wire construction maximizes electrical efficiency, significantly reducing voltage drop over long spans to ensure your LED or incandescent lamps burn bright. The rugged, weather-sealed jacket encapsulates a 2-wire conductor system (Black and White) to protect internal circuits from continuous vehicle vibration, pinches, abrasions, and road debris.

This OEM-quality harness delivers highly secure integration with your vehicle's main electrical layout. It features a reliable 2-plug design equipped with specialized 2 Position .180 Bullet connections on one side and standard .180 Bullet Terminals on the other. This molded-plug construction creates a tight, moisture-proof seal that blocks out harmful road salts, dust, and water, eliminating corrosion at critical contact points and maximizing your lighting system's longevity.
