Works Perfectly for My Light Bar Setup!
Size: 16AWG -10FT 2Pcs
The Nilight 16 AWG Wiring Harness Extension Kit made installing my LED light bar so much easier. The wires are thick, durable, and exactly the right gauge for a reliable connection. The 10-foot length gave me plenty of room to work with, and everything connected smoothly without any issues. Feels like solid quality, and I appreciate that it comes with a 2-year warranty. Great value and highly recommended for anyone wiring up off-road lights or accessories.
