Hi all. My 2004 E55k requires drivers side xenon bulb. Are they easy to change. And where is the best place to buy the bulb apart from dealer. What type of bulb are they?? Thanks.

As above, dont buy cheap ones, ideally you want to replace them as a pair otherwise you will have one really bright and the other blue/pink due to age.
