I installed a 4300k HID kit from suvlights.com about two years ago and they have worked great until the past few months. They sometimes will both flickerer very rapidly and even shut off while i am driving. They both do this but it only happens occasionly. My battery is brand new and all of the connections seem fine. I am not having any other electrical problems, so i do not think that it has to do with the electrical system. I would appreciate any advice on my problem.

 

Im thinkin its the ballast thats causing it to flicker. Do you know anyone that has the similar setup that will do a quick swap to test this?

 

If they are both doing it then I don't see how the ballasts could be the problem unless they are flickering at different rates.

If they flicker together, look at the power supply. A loose connection, bad crimp, or faulty relay may cause this.

 

they flicker at different rates and sometimes only one may flicker and others both do. I have relocated the grounds to new and much better locations and i removed the bulbs and reinstalled them. I also check all connections and fuses and everything was fine. I have not experienced the problem for a few days now but i will keep you posted.

 

One of my low beam bulbs started flickering and went off sometimes shortly before it stopped working. But mine came with the car so it might be different for you.
