OK so my stock headlight went out, Mercedes warrantied it and replaced the headlight entirely..

NOW I have headlights that are completely different colors!! Both HID but the new is more 4000k while the other like a 5000k..

Pic will be up asap, not sure how much good it will do..

Is it possible that the company who makes the mercedes headlight has changed??

They announced a new vendor for the Jan 2011 builds of the W212 E Class. The new bulbs are Osram although I think the burners and igniter is the same. You can find the announcement on the Daimler media website archives.

But it should be the other way around. The older ones are closer to 4300K and the new ones are now at 5000K-5500K. Did they replace the whole projector unit or just the bulb? The bulbs need to burn in for a while to get to the right color temp. I normally replace both at the same time. Anyway, wait a while and use it and then check again.

fwiw, I have one headlamp that looks slightly different temp then the other. But it's in the projector itself and it's some sort of oil film or something that's slightly discolored, or the ballast is not the same in each, etc.. Changing the bulbs makes no difference.

hid bulbs will change color as they accumulate hours. replace the older bulb and they should be close.

The problem is I like the older headlight color better!!

Yup, a so does the lens on the headlight ( they tend to turn opaque ).
