Well they are the standard HID kits with the wiring and ballasts that hook up like a normal low beam kit. It kept blowing the 10 amp fuse in the engine bay fuse box (only when I turned on the fogs for the first time). I replaced the 10 amp fuse with a 15 amp fuse and I have not experience the problem ever since. Should I go back to a 10 amp and see how it goes or with the 15 amp fuse be safe to stay with?
