After waiting three weeks for delivery of my led indicators, I've just fitted them, look bloody nice too !.. IMHO I've spent the last five minutes, switching the hazards on & off & going round the back to take a look !!
Fitted the same to my scrambler and carried out said "visual distance emergency light inspection" routine!
No, not the rubber pieces, and I was joking about "fallen off". You evidently don't have the (metal) pannier brackets fitted.
