My 2007 M6 has them, but they are almost too bright. I didn't even notice my F10 M5 didn't have the lights until i read this post... only time it bothered me when i was shifting on a tight curve... i assumed my wheel was just 180 degrees to the right... so i did pick the downshift lever correctly....
Also noticed they took away the lights on the bottom of the door seal(?) (where it says M5)
