Have an '09 C300 sport, (Canadian version ) headlights are HID standard, and the rear signal lights are red LED. I too have always liked amber turning lights for higher visibility, more noticeable, but I must say these red LED's on the white/chrome background are very bright and most noticeable. The one rear foglight feature is a weird one; wonder what the thought process was there, if any?
While I'm on here, has anybody swapped out the foglight 'bulbs' , dealer won't do it, & I can't find any videos on YouTube.
Thanks for any advice.

 

They should be the same
