You can make a generator from an old toy motor. Mount a 9-volt toy motor and connect its terminals to a LED. Attach the small pulley on the motor axle to a large pulley. As you crank the large pulley, the smaller one will rotate the motor at a fast speed. This will produce a current which will light a LED -- which in this case is a streetlight.
