I used the 14" LED Light Bar for my 2019 Can Am Defender HD-8 XT. A few things about the light bar. It has sliding mounting brackets that allow you to center the light where you need it. It can be tilted so you can put the light where you want it. It's easy to assemble. The holes on my UTV were 6 inches apart, this light fit perfectly. The wiring harness fit snugly under the dash and the switched was the exact size for my UTV. I am very pleased with the results. The Rocker switch has a light in it when the switch is off, the top portion of the switch lights up when the light bar is turned on. Make sure you wire this into a switched power source, If you don't it will kill your battery.

This wiring harness was as advertised, and was reasonably easy to install. The switch is good looking and functions well, and the overall length of the harness was adequate to get where I needed it to go. My only concern at all is the size of the wire used. The listing shows a 40 amp relay in the heading (which it is) and in the description it specifies a load under 180 watts (which would be 15 amps). The wire gauge however is 16 gauge. Most charts show that 16 gauge wire is approved for a 10 amp load under 20 feet long. As this is a 10 foot long harness, and my load is 120 watts (10 amps) I should be fine. However, I really would hesitate putting a heavier load than 10 amps on this harness.
Let me say again that this appears to be a well made harness, and I am pleased with the purchase. I would however advise anyone looking to run a load in excess of 10 amps, to look at a heavier duty harness. (I believe this same company offers one and I would not hesitated to go with them)

Reviewed in the United States on October 28, 2016
I wired up a 20 inch 126 watt LED bar with this, and after a couple months of use, the switch is holding up well. I didn't have trouble getting it wired up, even though I have very little electrical experience or knowledge. The switch fit into the factory slots on my 3rd Gen 4Runner. I did have to drill a hole through the firewall to run the wires through. Also, when installed according to the directions (directly to the battery) there is constant power to the LED switch, so it glows even with the ignition in the "off" position. Driving everyday, it doesn't draw enough to make a difference, but if you park for a week at a time, you'll probably want to unhook it! Thinking about wiring up another let of lights and will be purchasing another for it!

I ordered the complete kit for my Polaris RZR 900S from Amazon. MICTUNING 32" 180W 3B239C Curved LED Light Bar, Over head Mounting Brackets that attach to roll cage, PN: 6KLED BK1002 and Wire Harness, MICTUNING LED Light Bar Wiring Harness.

Ordering these parts made assembly quick and easy. My buddy came over to help me install the light bar on my RZR 900S. About 2 hours later and a six pack of Miller Lite, the job was complete and working perfectly!!

I really expected much less than I received from Amazon for less than a hundred bucks. My local Polaris dealer had two options for me that cost between $200.00 for just a light bar with no mounting hardware or wire harness and $600.00 for an OEM Polaris light bar kit which included everything I purchased from Amazon.

I would recommend this light bar kit to anyone who owns a Polaris RZR 900S.
If you can't tell from my review, I am very please with this purchase from Amazon.

The switch and wires are good and install very nicely on a Polaris RZR 800. Switch had a terminal pull out when I connected the wires as directed by instructions prior to putting it into the dash. I had to work to get it back in and hope it will stay there and not wiggle loose. I was just surprised it came out as I have just been wiring up my toy-hauler and have hooked and unhooked dozens of terminals form various companies as I customized my trailer. Might have just been a one of thing for this company, not sure. I like the light on the switch when it is on however I wish there was a small light on like the factor light switch so that you could see it at night when it is off.
Overall it is a good product.

I purchased the wiring kit to wire a 22" light bar on my 2013 F150 and it works great! It was actually better then I expected cause it was pre-wired for 2 lightbar connections!! This let me wire both a 22" in the front bumper & a 42" behind the grill.
The wiring is very well insulated and there was plenty of wiring to put the relay by the battery and run everything nicely into the cab. The directions are terrible but you can figure things out with some planning. I have attached the best wiring diagram I could find for the switch. It clearly points out each prong and what it does. This made wiring the switch up a breeze!
I will definitely be ordering this again when I install the rear led pods.

In order to install the switch in a factory button location I had to slightly modify the opening with a dremel, not hard at all. However there were no instructions provided and I cannot get part of the switch to illuminate when the ignition is on and or the parking lights are on. When I turn on the switch the other half of the switch functions but not when in the off position. Tried multiple combinations but the other option was to have the switch illuminated the entire time, even with the key off, which is not ideal. 5 Pins in the back of the switch, should be straight forward

This worked perfectly - I ended up purchasing a cheap Rocker Switch Holder Panel and installed through the firewall of my truck (which is plastic and designed for drilling holes for this purpose). I decided to wire this in so I can turn on my Lund 27021204 Stainless Steel Bull Bar LED whether the key is in the ignition or not. The harness switch has an LED built in that remains illuminated and makes finding it at night easy (I decided to put it in the lower right corner of the driver seat area at the bottom of the dash where a screw already existed to screw in the Rocker Switch Holder Panel. The Lund LED bar is super bright so I would be careful not to drive down the highway with this on unless you want to draw attention.

5.0 out of 5 stars works good used diffrent switches requires a fuse tap if u want it to light up when lights come on
Reviewed in Canada on June 9, 2021
the wiring diagram had diffrent color wires then the harness. the switches that came with it fit perfectly. anyone that says they don't prob bought the shorter wider switches that tacomas also use but if u are using a tall skinny switch spot they fit perfect. I bought switches that are push button not toggle and I connected the power for the main light off the fuse box where the rest of the dash lights get power so when my lights come on the switches light up with the rest and csn be dimmed or brightened like the rest then connected the grounds for the main led and lengthend then enough to ground under hood. u czn wire them so the lights stay on all the time even when truck is off or so they come on when truck starts day or night but the proper way is to connected to the panel lights so they work like oem. it's simple to do u just need to order a fuse tape and fuse box is right under dash slose to drivers door where I mounted my 3 switches. if the harness is for 2 lights you will likely need to extend the wire unless they are not going to be more then about 2 feet apart. I recommend a multi meter and basic knowledge of d/c current and wiring
