The color and light intensity of HIDs are different and if not in the proper hosing will create a glare for oncoming drivers because the light from HID bulbs is not intended to be reflected out onto the road. If you research it some you will get a better more detailed explanation. I would hate to see someone spend the money on one of those kits and then find out they are federally ilegal.
