This might sound a bit dumb, but my side turn lights on the back of the mirrors aren't working and they were a few days ago. I'm wondering did I push something to turn them off? I'm still a bit new to this benz and been playing with controls exploring... Is it possible to turn them off or should they always be on, and might be a fuse problem? I have a 2011 cls 550 / c219.... Thanks for any help....

 

Well, it's getting dark so, in park I start the car and turn the signals on and they work. Is this a function that works only at night? I thought they came on anytime day or night that you turn on the signals....smh
