Outstand Product!! 😉
Color: 14AWG-1 Lead
This is my second (at least) Nilight wiring harness. I wanted to re-do the lights on my Rhino 660. This makes it SO EASY! 👍🏼😉 And a hell-of-a-deal!! All I had to get was a "reamer" drill bit to enlarge the switch holes on my dash. Run the wire, attach the ends to the light, switch & power source, all done. I did add "shrink tubing" to my connections to add an extra layer of insulation/weatherproofing. 👍🏼

Definitely a good buy very professional craftsmanship
Color: 14AWG-1 Lead
As a retired master technician for Honda and all makes and models of automobiles this harness is a cut above the others is put together immaculately and anyone that can put a wire through the firewall I purchased my light bar to harbor freight 22 in great lighting but their harness kit was 56 bucks I paid under 24 this and it looked identical except the switch on this is actually much more appealing cosmetically and works well functionally just had to drill a hole in one of the blanks 4 switches in my truck made it fit perfect and has worked flawlessly since I put it in a couple weeks agodefinitely do your homework sometimes I find great deals at harbor freight that nobody can touch on Amazon but then other times vice versa Amazon has a great product at a great price compared to harbor freight in other retailers

Perfect for roof LED light bar
Color: 14AWG-1 Lead
This worked great for wiring a 50" LED light bar to the roof of my SUV. This kit conveniently includes a relay, switch with backlight, and fuses. I used a step bit to drill the pilot hole for the switch and worked my way up until it was the right size. I zip tied the excess wire and it made for a clean install. My only complaint is that the ring terminals were too large for the battery but it was easy to crimp smaller ones on.

Good harness
Color: 14AWG-1 Lead, Color: 14AWG-1 Lead
I bought this for the nilight 12in bar. It came in the same box and right on time. It easily connected to the light bar and into the engine. There is a lot of slack between the battery terminals and the bar, but it’s understandable if maybe you wanted to mount this on the back of your vehicle. I wish there was more slack between the relay and the switch, as having to go from the battery through the firewall and into the cabin requires sufficient length. I ended up getting rid of the circular switch that came with it and it’s complimentary connectors to replace it with my own rectangular rocket switch that fit better in the cabin. Overall good product. I’d advise to wrap electrical tape around the quick disconnect to prevent any weather wear.
