Nice post! I'm actually thinking about strategically placing a few low powered LEDs (Knog Skinks for example) in such a manner that they will light up reflective tape already on the bike. Fork mounted lights can light up reflective tape on forks, rims and spokes. Looking for more side visibility and shape recognition from a distance on the cycle paths where there are fewer bright lights, no automobile headlights.......and a lot of cyclists and pedestrian that insist on going ninja. I'm guessing you may already have tried this yourself.
