Look pretty simple and don't have to do all the retrofitting.

 

I put them on my previous quad, a Polaris Sportsman X2 500 and they did make a difference. On the Can-Am I have now I recently installed a LED light bar that I got off of Amazon. Look in my pictures under my user name for a couple of pics of the difference. I'm going riding tomorrow and may get a chance to try them out in night riding.

 

Your ATV has the relay and harness already installed?

Some are "want to be" HIDs. True HIDS like I have come in a KIT that range from $100-$200 that have more parts to it the just a bulb swap. Arctic Cat ATV & UTV HID Converison Kits - Super Bright, Plug-N-Play! You cant just put HID bulbs in a stock ATV with out the rest of it. The stock ATV wiring can not handle it.

My friend bought Blue colored Halogen bulbs in his ATV and sled and though he had HIDs. LOL

The Bulb is just 10% of the conversion kit as you can see in the below pic.





Here is a pic of my 350 with the HIDs and yes they are nice at night vs stock. The harness and relays kit parts fit under the seat.

 

I almost laughed out loud when I read "Makes your lights looks more luxurious." I guess that's one reason to get them. All the HID lights I've seen before were in kits like TLC posted.

 

X3 LED lights and true HID lights require their own wiring.
