I have a minor issue that I'm almost ashamed to post. But my right hand mirror/turn signal on my 2013 Stelvio vibrates so much it keeps jigglng the turn signal bulb loose. Is there a way to tighten the mirror on its stem? It vibrates quite a bit more than the left mirror. If that is not do-able, any suggestions on tightening the bulb. I tried to bend the small metal contacts twice but that doesn't seem to work very reliably.
