Okay, so this is a bit random, and it doesn't keep me awake at night, but has anyone else seen left or right fog lights on Mercedes models flickering on and off? I must have seen around 10 in the last year. They catch your eye because - apart from the fact the driver probably shouldn't have switched them on - one of them isn't working. And then it goes out, comes on, and goes out again.
I've seen this on C-Class and E-Class models. Anyone else? Or should I cut down on the caffeine???
