All great ideas everyone. I'll shop around at the bike shops and look into the snap bands, I'm liking the easy on and off capabilities.

LED blinking lights are good too. I see a bicyclist each morning that has a headlight that blinks High and low, which seems to work well. Not sure I want a headlight though. lol.

Glowsticks I carry in my pack, but I don't want to spend that money every few days if I can't turn them off.

I'll let you know what I come up with and hopefully post an example using it.
