Step up and get your own "dynamo hum"...(FZ). All jokes aside, its a simple dynamo light mounted to a Planet Bike light bracket. On about 6 cranks I get 20 to 25 minutes of light.
There is a 3.6 volt NiMH rechargeable battery that comes in the light. SO, by free I refer to your out of pocket cost on batteries.

The law (here in Arizona) says you need a forward facing light visible from 200 yards. This covers that and I only need a rear red reflector. So, I'm now battery free!
