Re: How the ?!
Well, for the light mount, the big arrow in pic points to what mounts onto your bike. Its like a locking clamp. then the small arrow is where the light mounts.
I'm curious about that generator too, I've read they're kinda weak, but I'm not sure.
For brake lights you'll need a switch in your brake handle, someone should know where to get one. I have no idea at the moment.
That tank looks cool, cheap too.
