I have never noticed the lights do anything that are mounted on the front of the side mirrors on the end. Has anybody ever notice if they blink, turn on, or what do they do?
They light up (blink) when you use your turn signals and (I think) they blink when you lock / unlock your car.
yep your right, they do blink when you lock your car but they surely do something else. I never noticed them blinking when I use the turn signals.
I can't see mine when I'm driving, perhaps that's why you think yours don't do anything? If you actually get out of the car and look at them while your blinkers are on, they should flash. If they don't, you have a problem. But if you just assume they aren't doing anything because they're out of site from the driver's seat, well...then you have a different kind of problem
