Bi-X: W203/CL203 OEM Bi-XENON Upgrade, Auto-Levelling & Programming thread
I have the original Factory single xenon in my 2001 C320. I know for a fact that the xenon bulbs change the more you use them. When I first got mine it was hard to tell that I had xenons. Looked closer to Halogens but alot whiter... After 6 months of use I noticed that the bulbs changed to a bluer color and now after 2.5 years they stay blue. Just remember if you need to change a bulb it's better to do both at the same time or they won't match.
I need to use my xenon foglights more so they can catch up. They look a little whiter than my xenon headlights.
euro versus US spec bi xenons have a different lightpattern BUT use the exact same bulbs...and projector mechanism...
greetingz,
Is this normal for my car?
Thank you.
This is the normal US spec W203 bix lightpattern:
greetingz,
What's the distance from the floor to the top of light cut off?
Thank you again.
thanks a lot..

Also, I believe there is a setting to turn the lights on all the time in the lighting menu (day light driving lights) that you might want to play around with.
thanks guys. i indeed already brought to dealer to have them set to xenon setting. and where can i find the day and night light settings section ?
Hmm I like the 8k one!
Yup it looks HELLA CLEAN! You know how when your bixenons kick in they are really blue? Well this is how Mike's bulbs stay, a nice blue tone
where is a good place to buy these bulbs... and how much $?
From EuroRev...I believe they wanted to start a group buy

The 10k ones illuminated the road best of all 3.
