I have a bike. I don't use it. This needs to change.
Problem was, my commute is mostly during the evening and in winter, this is in the dark. So, for legal and safety reasons, I haven't commuted under my own power for a while. Now, I can.
I wanted a rear light that used AA batteries so I can standardise on them for all of my kit. I will be migrating to rechargable ones shortly, once my current stash of AA batteries runs out.
The problem with this light is there is no real attachment point for it. There are some mouldings on the inside to hold bolts in place but nothing else.
However, the existing reflector on the bike has some sort of bracket holding it on. Wheels began to turn and ideas were formulated.
