hey guys, i recently got hids in my car. i have had one problem come up.. they flicker all the time.. everytime i come up behind another car, i can notice that they flicker.. but not to the point where they actually flicker on and off.. its jus a lil flicker. sometimes i give the car a rev and they go away.. but it literally does the flicker thing all the time. any suggestions what it may be? kevin
