I have nothing but great service from this company, have used their hid kits in multiple cars over the years, and sure had bulbs and ballasts go out over the years but I got to say they will work with you and replace bad bulbs and ballasts and help find the problems with you, one of the only hid company with a real lifetime warranty that will make it right, so if you are looking for a HID kit check out this company they are the real deal
