Knott-

DH has the BikeGlow thing from REI. He has it wrapped around his frame and it works well enough to mark him as a bike. I like that it can use rechargeable batteries, but the battery pack makes an annoying whine. I have very good high frequency hearing- others might not notice it.

I use a green Fibre Flare on my downtube, sort of llike a poor man's DLG. It uses rechargable batteries, and casts a pretty bright glow on my legs, feet, and the ground. It's totally self-contained, and easy-on, easy-off. It's available from any bike shop that has a J&B Importers account.

I like frame lighting in conjunction with Lightweights on the wheels. They weigh nearly nothing, and have no noticible effect on handling or acceleration.

Enjoy your new commute, and stay safe!
