My C230's headlight is 'foggy' such that the right headlight appears to be higher than the left side, but I had the alignment checked and it's aligned correctly - they just said it was foggy. Any ideas what I can do to fix that?

 

I honestly don't know what its called, but most auto parts stores should carry a cleaner to un-fog your headlights.

 

The left headlamp is aimed lower on purpose to prevent blinding oncoming driver.
