Hi, I have a 2004 CLK 320 and my xenons arent working for the passenger side. It would flicker a few times trying to turn on and then it would completly turn off. I had one of my buddies turn them on while I look and the driver side lights up fine and i look at the passenger side and it flickers. When it flickers it doesnt look like hids/xenons. It looks like it is a very cheap yellow color like they were halogens. Does this mean that I need a new bulb and if so what size are they? or would I have to replace the whole ballast and ignitor? Thanks

 

no one knows??

 

I had the same problem and they had to replace the whole cluster. It was under warranty, though.
