Changing E53 Xenon Bulbs
 

This is very easy as long as you don't drop the screws!

First remove the rubber bellows seal and 3 screws from the round cover. The bellows is held by a "U" clip see below.

Replace the bulb making sure to align it correctly in the socket. Attach the bulb retainer. Attach the HV wire and make sure it is firmly fixed in place. Reinstall the cover and attach the bellows back in place using the "U" clip.
DONE!
