Braking Activated Rear Bike Light
I got bored and decided to liberate my old dynamo light,
so I gutted it, and wired the bulb to 3 AAA batteries and lead 2 leads out the side of the light casing,
I then ran the wires to either side of the disc caliper, for the arm that WOULDN'T be moving i used a bit of metal which the cable tensioner... tensioned and on the arm that moved i just taped some tin foil to the end (same for end of other arm also)
and veola! a craply made light (does work and is kind of rain proof as havn't had any problems yet)
slight warning, if you do attempt this i had to make little washers out of the tape as i didnt have rubber ones, as it makes the whole brake live
