They're not exactly HID. They are just xenon bulbs that burn hotter and are brighter than the factory halogens. I still havent gotten a chance to put them in yet but i will definately post some pictures of them once they are in. I think that if you want the HID's you actually have to buy the entire housing and it comes with a balast too. I have heard of guys buying the charger fog light coversion kit and that seems to work.
