The light is pretty awesome, has a few different sequential blinking modes and very bright when it detects you're braking. Going to fab my own bracket sort of out of some metal from the local hardware store and drill 2 holes in it to attach where the bolts are on the back of the board. I'll put up some pics once I'm done, but should be easy with just a drill.
