Here you go, Peter Jon White knows just about everything about dynamo bicycle lights:

connect a dynamo from the wheels to the battery
the rotation of the wheels will charge the battery
connect the output of the battery to bike lights
you need a generator or alternator and a battery.
also, a light sensor or timing circuit is useful

when the light intensity drops below a certain point, it closes the circuit to activate the lights

alternatively, you can have the lights come on a timer

of course there should also be another on/off switch to turn on when you want to ride it, because you wont want your bike lights to go on when your bike is just sitting in the garage.
