I've seen this video before, cool idea indeed.
The problem with bike illumination is the purpose: see yourself or be seen? While very high output designs are great for seeing they are a pain in the *** when you look at them. I remember that i had to drive a few kilometers down the kanal to get to work. In october this was quite difficult, since early in the morning it was nearly complete darkness. Those LED lights were cool to have, but never the less useless if someone is coming from ahead and has some of them too: we were both nearly blinded by each others light and nearly crashed.
Now i use up to three different types of lights: the standard lightbulb, doing nothing for me but since it's required
, a medium output battery powered device and for some rare occasions i even use LED headlamps.
I would really like to see the system from the video in use here, i think a lot of accidents involving bikes and cars could be avoided if these were used. And they don't interfere with other peoples vision.
