I am new here. So please overlook the unnecessary BS, I have a 2006 tundra, I have installed the HIDs from EBay which may have been the problem, but, The 2006 Tunda headlights receive a less voltage for daylight driving. The HIDs burned bright all the time. The halogen bright lights (with HID kit) are sorry. The lights confused the computer and it would not switch to the bright element. but if you pulled the turn signal for flash to pass the halogen bulbs would flash on.
