Review on 🔦 LAMPHUS 13' Off Road LED Light Bar Wiring Harness Kit: Waterproof Switch & Mounting Bracket, 30A Fuse 40A Relay - Perfect for ATV Adventures! (USA Warranty) by Alex Prince

This kit includes everything you need to connect your lightbar. I have previously purchased another switch as the one in this set looks a bit silly which is not a problem as the switch is not permanently attached to the wiring harness so no cutting or splicing is required. The attached schematic was easy to read. A word of warning for people like me who have little to no experience with switchable relays. Check the wiring diagram. I installed this on a spare battery in my house so there was more room for error while learning how to wire everything up properly before installing it in my truck and I'm glad I did. It was a lot easier to see what I did wrong the first time and fix it, and also put out a small fire I started without following the pattern. Although everything is fine. I only destroyed the 18 gauge wire between the battery and the switch, and none of the wire harnesses were damaged by my mistake. If you don't have a power supply that can be plugged into the car, not long enough to bridge the distance between the switch and the battery. Not a big deal considering that replacement cable reels are cheap and plentiful, and chances are you're probably planning on doing some amount of custom wiring anyway if you're installing a wiring harness and lighting system. In the end (when connected properly) this harness has absolutely no problem powering a 20" 120w LED bar and it correctly lights up the small LED in my switch when the system is powered on, and also turns off the switch LED when the system is powered off. Will definitely be back to buy more of these when I inevitably end up adding a third and/or fourth light bar to my truck.
