Reviews for Quadratec Anti Flicker Pulse Width Modulator for 07-18 Jeep Wrangler JK

Bought these to replace defective ones I had received from another supplier. Worked great and completely fixed my flicker issues. Well worth the price.

I assume they work, as I have had no flicker (I never tested without them), but it is my understanding, that Jeeps are known for flicker without them.

AMAZING!!!! I am skeptical of most things - especially when they are claimed to be a perfect solution. But these are exactly what they are claimed to be. They ARE your solution to flickering headlights. I have been frustrated since upgrading to the KC LED headlamps - but now my problem is solved. Perfect functioning headlights! Thank you!

First let me say I had tried 2 different other anti flicker devices from other sources that 'claimed' to work. Needless to say they both were returned. I was struggling to solve the flicker problem for the Purple Halo Opar LED lights that I added to my wife's JKU. These solved the problem!!! Thank you Quadratec! (I was about to drive it into a tree to get them to stop.)

I bought these led lights off eBay and they are nice unfortunately for me the anti flicker harness and adaptor were very poor quality, so I was able to get a partial refund and I used that money and bought this Anti Flicker Pulse Width Modulator from quadratec it's so awesome literally plug and play and it's waterproof, my other cheap harness wasn't even waterproof and the wires popped out when I tried installing it this plugged right in and everything worked well.

It just arrived today and I installed them right after I opened the package. Before my LED headlights on my jeep would flicker . After I installed these my LED headlights no longer flickered. Very easy install no need for instructions. It didn't come with instructions anyway.

Bought these to replace the JW Speaker modulators that only lasted a year. So far, they perform very well when the lights are on. I can't really see any flicker and there is practically ZERO delay when you flash the high beams. My daytime running lights (high beams) were enabled by the dealer to comply with local laws and they do still visibly flicker so I deducted a star.

These installed very easy and work fine, however the harness does not lock into the factory plug. A little electric tape should hold it for a while.

The antiflicker harness workes,but there are a delay when you switch from high beam to low beam.the high beam hang on about 3sec after you turn of the high beam on my 2012 jk. And it's not possible to flash with the hig beam any more because of the delay!

Very disappointed they worked great for 4 months then the one "burned up" and now the other is acting up so I have no lights and I can't take my daily driver to work until I get a different set I ordered these September of 2017 and they are already bad
