Hello guys!

I own Mercedes W204 Coupe 2012 and after little accident i have to replace my front right headlight.

Post a picture of the front of your old and new light
You probably got sold a halogen light instead of xenon or vise versa.

Perhaps it has something to do with this thread https://mbworld.org/forums/c-class-w...ts-wiring.html


*maybe save yourself the hassle and return the headlight and buy one from your model + year

Yes, i think this might be it also after looking at this specific post in another thread:

The black connector is what OP has in that picture
"halogen lights connector (yellow) has 10pin with 10 wires and Bi xenons has 14pin with 9 wires going in"

or is it a combination of both... Pre facelift bi xenon - facelift xenon? lol

"how do i connect a pre facelift bi xenon headlight to a facelift bi xenon connector" is probably the question awaiting an answer
