Here is my version. I used what looks like the same "bar end" light, but I mounted it in a CO2
cartridge. Since empty CO2 cartridges are a biproduct of bicylcling, it seems more fitting to
use them than to use machined aluminum housings on a rat rod.
Personnaly, I wouldn't pay a dime for a set of cantilever brakes. I don't care how cool they look, they are a pain to adjust compared to the simplicity of V-brakes. But they look definitely very cool. As for the lights, agave that is awesome work and a great idea.
