I installed a headlight modulator and a break light flasher, hopefully I will be a little bit more noticeable on the road. I made videos of both working. http://home.comcast.net/~jdthorstad/headlight_modulator.mov and http://home.comcast.net/~jdthorstad/breaklight_flasher.mov

i've seen the brake light things...they are cool, definitely makes me notice bikes more.
as far as the headlight ones...makes me want to go head on with the bike!
