Just a quick one... was hoping you guys could help me out and tell me what these are for?

This is some kinda clip on the pillion seat strap... original purpose intended?

Under the pillion seat, i found this strange device... i am some how supposed to use it to lock my helmet to the bike??
Oh i also would really like to know if this is supposed to be like this...

This bit of black fairing is rather loose compared to the same bit on the opposite side. I was wondering if i was missing a fixing or is that normal for all NC30's?
Ok ok ok... 1 laaast thing....
Tonight i changed my tail/brake lights(lhs brake light not working) from the original jap spec 18/5W to UK spec 21/5W. Is this going to be a problem seeing as the bike is a Jap spec model?
Any help/advice is always appreciated!
Thanks everyone!
