Just finished upgrade foglight project for my W211.

I love it man. Whats the source for the projectors? Is the housing the same? Check the seal for the long term if it allows dust or water to enter. Nice job

Any beam pattern shots?

anwarm14 & Bayarea, after installed the hid projector foglight, your car looks cool and much different. I bought H11 Projector (photo) made for E320 (2003-2006) replacement for $80 on ebay. I use the original foglight housing and removed the inner chrome before installing new projectors for foglights.
We only need some cut from the replacement part that came with projector. PM me i will show you more detail, where to buy projector and how to do it.
