East Penn’s 4-conductor trailer wire delivers all the signals your trailer needs: running lights, brake lights, turn signals, and ground. Multiple colour-coded wires (yellow, white, green, brown) parallel-bonded together stay together during installation, then separate cleanly at the end for final terminal connection.

Built to SAE J1128 and SAE J378 standards with 100% copper stranded core for maximum conductivity. The flexible construction makes installation easy, whether you’re running wire along your frame or through conduit. Available in 1000-foot bulk spools for large projects.
