One of the most popular things happening in the Jeep market right now (other than Vision X LED Off Road light bars) are LED headlights. Several companies make a light that will fit the opening of the Jeep that uses a 7″ round headlight housing, but nobody makes one specifically for the Jeep. This is a problem because the JK Jeep Wrangler (2007+ Models) use a special CANBUS functionality built into the lighting circuit. This is a good thing because it is a more intelligent design to control the lighting but it makes modifying the headlights a difficulty. This is how to fix the flickering problems you will encounter when trying to install LED headlights into your JK.

This is the only thing you need in order to install flicker-free 8700 LED headlights into your 2007-2014 Jeep JK.

Without doing any modifications to the wiring, if you install LED headlights, like the JW Speaker 8700 Evolution, or the Truck-Lite 27250C the lights will flicker, flash randomly or strobe. This can cause headaches for the owner of the product because it will seem like the product is defective.

  1. I dont have a problem with the lights flickering but im having problems with the brights. When I try to turn the brights on, one or both of the lights turn off completely. Will the new harness solve this problem?

    1. Hi Greg, I haven’t heard of this particular problem happening on any other Wranglers before, but it may be caused by the CANBUS system. I would give the anti-flicker harnesses a shot and see how they go for you.

    2. Having the same exact issue. No “ant flicker” harness has helped. Did you ever resolve this?

      1. We’ve never seen a set of headlights that cannot be fixed by a standard anti-flicker harness. My advice is to use a decent set of headlights instead of Chinese knock off headlights. The real JW Speaker headlights will not flicker when installed properly.

    1. The way this harness works, if you install it with a DRL-equipped Jeep it will actually flicker worse. If you have the DRL function, really your only option is to use this harness and never use the auto-light function. Always have it set to headlights ON every time you drive the truck. This isn’t so bad though since the JK headlights will auto-time-out and shut off after a minute or so when you get out of the vehicle.

    1. The back side of an original halogen bulb gets up to 155 degrees, most LED bulbs reach temps of around 175 – 200 degrees. This is not that much of a difference. I know that it takes more than 300 degrees to damage the actual plastic housing. So, I’m not sure what you think you might melt. If you’re concerned just tie soft plastic things up and out of the way.

      The GTR Lighting GEN 3 bulbs reach an average heat sink temp of 171 degrees. You can read more about that here:
