Truck-Lite 50344 – 50 Series 456” 1-Plug Flat Right-Hand (RH) Side Turn Signal Wiring Harness | Straight PL-3 to Blunt Cut, 14 Gauge
The Truck-Lite 50344 (50 Series) Right-Hand (RH) Side Turn Signal Wiring Harness is an ultra-long, commercial-grade electrical assembly designed specifically to route turn signal and side marker power down the extended passenger side of trucks, trailers, and long-haul fleets. Spanning an impressive 456 inches (38 feet) in length, this premium 1-plug harness delivers continuous, clean power from your central control source all the way to your right-hand side lighting configuration, ensuring proper signaling, increased roadway safety, and complete federal highway compliance across maximum distances.
Low-Profile Flat Design Built for Extended Right-Side Routing
Extended right-side wiring paths are subjected to intense environmental exposure, wind resistance, and tight frame-rail clearances over long spans. The Truck-Lite 50344 features a low-profile flat cable configuration that easily slides along the vehicle frame rail to save space and minimize friction. Built with heavy-duty 14-gauge copper conductors, this 3-conductor harness protects against voltage drops and resists internal electrical strain over its 38-foot run. 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, green, and white lead lines directly into a main junction block or central distribution system without requiring unsafe intermediate field splices.
