oem hid xenon-one yellow, one blue. please help
Can somebody please help me. Im at wits end with having one bright blue headlamp and one dull yellow headlamp.
I have read about the burn in process etc. but this cant be the case as i have swopped the bulbs from left to right & nothing helps. The drivers side remains yellow and passenger side remains blue. Even used two other bulbs and it still remains in the above order. The previous owner did have minor collision and the drivers side headlamp was replaced-this is the only infomation i have. What will i need to change/adjust to get the both to match as i know for sure its not the bulb? oh and i also tried cleaning the inner of the projector glass of the older headlamp thinking there could be a build up of something but that made no difference at all. any help would be appreciated. thanks in advance.

its a w203. i havent tried swapping ballasts yet, will do so soon. im just afraid that if its not the ballast, then im in a dead end as i feel if it was a faulty ballast, it wouldnt power up the light at all. i dont know...thats just the way i see it.

I have the same problem. Dealer replaced the driver side headlight unit after the glass was cracked. Now I have something between white/yellow color on left side and "standard" blue on the right side. G550

also measure voltage and make sure that it is the same on both sides (for both headlights) right before the ballast (unplug ballast before measuring). do not measure voltage after the ballast as you will burn out your ohm meter (unless you really know what you are doing) and short your ballast.

When you just start the car and lights just turned on, is the problem light yellow or it stays for 10-20 sec bright blue and then turned yellow. That is what my light does on start up.

I have the exact same problem:
W208
I turn on the headlights, both turn on in the normal whitish colour...
Within 10 to 20 seconds, one of them fades to a yellowish/brownish halogen-type colour.
Mercedes changed the bixenon bulb; makes no difference.
They said it would cost over $2,000 to fix as the whole light fixture (ballast, power control, etc) needed to be replaced.
But it's so close to working properly, and clearly the charge works for a moment... but I think there must be a way to fix it for a more reasonable price, since it appears to be just a simple loss of power.
If anyone can figure out an answer to this, I'd very much appreciate it!
