Product developement

I think theres a bit of detail missing from your survey.
I use batteries, not b/c I like them but b/c they're least of evils. The type of light I got needs more power than a dyno can provide. Solar charge would be great, if it could keep up with the demand. If I were to switch over to high power LED, maybe a dyno would be enough. Or maybe a full/dipped solution? I don't need full power throughout the commute, maybe I could run a dyno with a battery backup. Dyno to supply running lights, and a trickle charge to a battery. Then have the battery to supply the lamp when running on full intensity.

I leave my lights on the bike, but I'm lucky enough to have secure storage at both ends. Behind locked doors at home, behind a locked gate and CCTV coverage at work. If I had to leave the bike at a public place, I'd want both light and battery pack to snap off easily - or to have a fairly tamper proof attachment to the bike.

Something I'd really like to see is a rear light powered by parasitic power. It'd be real slick if you could stuff a seat post with piezo crystals, and then use the power of compression to power, say the rear light.
