Truck-Lite 51342 – 50 Series 2-Plug Right Hand (RH) Side 413 in. Turn Signal / Mid-Turn Harness (16 Gauge, Flat Cable, Fit 'N Forget S.S. to .180 Bullet Connectors)

Keep your commercial trailers and heavy-duty fleets operating safely with the Truck-Lite 51342 50 Series Turn Signal & Mid-Turn Wiring Harness. Specifically engineered for right-hand (RH / Passenger Side) installation, this extra-long 413-inch (approx. 34.4 ft.) harness offers an extended reach ideal for seamless routing along the frames of large commercial trailers, tanks, and vocational vehicles.

Built to survive the most demanding over-the-road environments, the 51342 harness utilizes a low-profile flat cable design. This flat construction makes routing smooth, clean, and less prone to pinching or snags during installation. It houses three 16-gauge (16 AWG) color-coded conductors (Brown, Green, and White) that deliver optimal power to mid-turn indicators and marker lights while minimizing voltage drop.

The harness features premium, molded connection points designed to block out environmental threats. On one end, it uses Truck-Lite's signature Fit 'N Forget S.S. (Super Seal) connector to provide an airtight, corrosion-proof seal at the lamp interface. The opposite termination consists of premium .180 bullet terminals, making it highly compatible with standard heavy-duty lighting layouts. This ultra-reliable seal actively protects inner circuitry from water immersion, harsh road salts, and continuous vehicle vibration.
