My 2001 E320 4Matic has different color of Xenon headlamps now for some reason. Does any body know how to fix this or know the reason why one is bluer and the other one is "yellower"?
One bulb has more "hours" used than the other. No fix besides replacing both bulbs with new ones. This way you can be sure both bulbs are in the same span of their useable life. The older the bulbs get the "bluer" they will appear
