Very interesting post. My gf totaled my 04 X5 with self leveling and adapting HID lights. I got a newer 06 X5 with regular halogens. Is there a way to put the HID headlights from my HiD 04 X5 on my halogen 06 X5 and make adaptive self leveling HIDs to work? Is the wire mising? Can i run a wire? Self leveleing and adaptive HIDs are so nice in turns on a curvy road. Really improves visability and safety. I miss them. After market Hids dont turn left and right into turns so I really dont need them. What i really need is the adaptive turning feature. Please advise!
