The only "Silly" question is the one that doesn't get asked !

I can't say I ever noticed any excessive vibration.
I assume you've checked the obvious - that they are "popped" into the Housings correctly,
( they "pop" out - If you pull the outer edges away from the pod they will swing out of the pod,
to allow access for changing Indicator bulbs and accessing screws for taking parts of the Fairing off ),
and that everything feels nice and "tight" ?
The only think that I noticed was that when adjusting the position of them they were quite stiff to move,
and ( being an ex Demo bike ), the right hand mirror glass had been cracked by someone trying a bit too hard to adjust them !
