Hi there. I have an opportunity to pick up a set of pre-facelift bi-xenons for the W221 about the same period as the standard halogen headlamps on my car complete with the ballasts.
Can someone please confirm if the current standard headlamps can be swapped out easily with the bi-xenon ones in terms of all the connectors being there already or is a new or extra wiring harness required on each side?
Also I assume the car will need some Star coding? Is that quite straightforward?
Many thanks.
