Looking at rear light mounting for the Supernova Tail Light.
I'm thinking of mounting to the right hand side rear rack stay. I don't have enough space on the seat post or under the seat clamp due to saddlebag and I don't really want to use p-clips on the stays.
I'm thinking of removing the 2.5mm bolt of the light and then somehow directly attaching it to the rack stay.
The rack stay takes a 5mm threaded bolt and the Supernova 2.5mm unthreaded.
Could I get a suitably long 2.5mm bolt and use washers to fill the space inside the rack stay? Or I have seen these shoulder screws but not sure if I could get the right size.
