you might have the wires crossed where they plug in the factory headlight plug on the high beam side. i dont know if thats it just a guess, when i installed mine it said make sure the pos and neg plug into the pos and neg in the factoy harness i had to use a test light to figure out witch was witch cause both wires where black. if it didnt do it before the hids its gotta be something there try unhooking them see if it still does it...
