Thank you Gilly.

When I wash the car I see water spots in side the light, and becoming steamy.
Only driver site. On the top of lens I see black staff is coming off.
I just get this car last Mont, is very new for me. A lot of technology is dramatically changed.
For my 190D I replace the lens when I get hit by stone.
I replaced bulbs on ML for new one, Sylvania – Silver Star very bright. 4000k
HID – starts 4100k.
May I need to pure the glue between the lens and body of the headlight?

Best Regards.
