Odd noise from W221

So I have an odd buzzing noise intermittently coming from the head light switch to the left of the steering wheel. It comes and goes and only comes when the head lights are on. I have facelift headlights, which I'm thinking is the culprit, however they have never done this before.. and what on earth would be buzzing? (should I be worried about something catching on fire?)

The passenger side headlight appears to be flickering sometimes also. The headlight itself, as if it loses power for a second.

Any thoughts?!

If you have a W222 then your in the wrong forum buddy... there is a W222 section, try posting in there and maybe you'd get a faster response.

I have a W221. Looks like the title cut off and said "W22" with no last digit, I have fixed the subject.

Thanks

BUMP, still having this issue, anyone have any thoughts?

I have determined it is not coming from the headlight switch itself, but sounds like it is coming from the very back of the "under dash area" where it meets the floor/wall of the car.
