I've lost my flashlight before.
I need a backup that stays on the bike and highly theft resistant!
I just ordered some of these and they promised they would get to me on time. I love the technology of the "flipping" magnet to produce electricity without those horrible "rub on the tire" generator/dynamo lighting systems.
However, it truly is a "backup" as the light isn't continuous, but flashes for every revolution of the wheel. Must look like a strobe light bike at high speeds!
Here's the manufacturer: http://www.freelights.co.uk
