Left and right xenon different hue/color
Just fixed one of my xenon headlight (passenger side). dealer ordered new headlamp unit and new bulb.
When I reached home I found that the passenger side xenon (right side) is more yellowish than the driver side which is more bluish. Is this normal for NEW xenon headlamp and will it change to bluish in color with time?
this is the part no. for the bulb that the dealer ordered
1 910139-000001 bulb
1 209-820-36-61 lighting unit
Thanks

Almost sounds like you have 2 different temperatures of bulbs there... I've never heard about 100 hours for the bulbs to adjust or whatever but if it's true, I'm wondering why the Dealer's parts guy didn't mention that the colors wouldn't match with your stock bulb...

I began to suspect that maybe he gave me a used xenon/ bulb. I talked to my friend and he told me he also didn't have good experience with this dealership. During my 2-week stay there, they managed to put some minor damage to my car too, though they did fix it.
