Truck-Lite 50343 – 50 Series 180” 1-Plug Flat Left-Hand (LH) Side Turn Signal Wiring Harness | Straight PL-3 to Blunt Cut, 14 Gauge
The Truck-Lite 50343 (50 Series) Left-Hand (LH) Side Turn Signal Wiring Harness is a commercial-grade electrical assembly designed specifically to route turn signal and side marker power down the driver side of trucks, trailers, and utility fleets. Spanning 180 inches (15 feet) in length, this premium 1-plug harness delivers continuous, clean power to your left-hand side lighting configuration, ensuring proper signaling, increased roadway safety, and complete federal highway compliance.
Low-Profile Flat Design Built for Left-Side Routing
Left-side wiring paths are subjected to tight frame clearances and constant exposure to the elements. The Truck-Lite 50343 features a low-profile flat cable configuration that easily slides along the vehicle frame rail to save space. Built with heavy-duty 14-gauge copper conductors, this 3-conductor harness protects against voltage drops and resists internal electrical strain. One side is outfitted with a factory-molded Straight PL-3 plug to establish a weatherproof, corrosion-free seal directly at the lamp connection. The opposing end is Blunt Cut, allowing technicians maximum flexibility to cleanly strip, custom-splice, or hardwire the brown, yellow, and white lead lines directly into a main junction block or central distribution system.
