Nice wire kit
Used this wire kit for my light bar on my SXS and it worked perfect. Used these kits for multi different ATVs over the years for light bars and they are just easier and cheaper than trying to buy the parts and pieces for the wiring and switch.

Great harness!
Awesome product, works great with my auxbeam 50" light bar. I have a 2012 Jeep KK and the switch cable was a bit short, but I was able to make it work. Not the sellers fault, it's a universal product. The only thing I didn't like was the switch light stayed on all the time when you follow the directions. Yeah it's a minimal draw but it bothered me. Another reviewer, Randy, said to remove the wire from the #6 pin on the switch to stop the light from being lit. This works perfectly! I'm thoroughly impressed with this harness as it shipped with everything I needed to adapt to my specific install.

Takes the guess work out of wiring LED LIghts on Polaris Ranger
This Nilight LED light bar Wiring harness almost installed itself. I was familiar with the simplicity and convenience of using this harness from an earlier application last year adding LEDs to the ROPs of my KUBOTA Tractor. This time, I installed this harness to 2 LED Lights that are attached under the rear brush bar bumper of my POLARIS Ranger UTV. The headaches of trying to figure out relay wiring, Rocker Switch wiring, and fuse protection are eliminated with this Nilight Harness. I opted for a 12AWG run, obviously an over kill for the 2 Naoevo brand 7inch LED Light Bar, 240W (Light out put equivalent) 24,000LM Offroad Fog Light Driving Lights LED Pods with Spot Flood Combo Beam, Waterproof Led Work Lights (also from Amazon) that I installed, but if I add additional LEDs later, I can tap into this harness with no worries. No, I don’t work for Amazon, Nilight, or Naoevo. I’m just a family man who appreciates decent products that last.

So simple a cave man could do it.....
Purchased to go with my Nilight 37 in LED light Bar. Very pleased with the harness and switch. The harness comes with an in - line fuse and relay. Super easy to install with the only thing I needed was electrical type to provide additional weatherproofing to one required connection and a few zip ties. All connectors and spare fuses provided along with simple to follow instructions for those not familiar with 12 v wiring. The wiring length is enough for most any configuration / location of switch.

Great product. Switch wire could be longer though. Was fairly easy to extend it with some spare wire.

Muy útil, creo que debería ser un poco más largo las dos terminales a la batería. Pero es excelente.
