FS: Dynamo (generator) powered bicycle light

New German made dynamo powered bicycle light front and rear. Uses the
mechanical energy produced by your turning wheel to convert to
electrical energy. Produces 6 volts and powers a 6 watt light. This
would be a terrific addition to a city commuter or long-range tourer.
$23 plus shipping. This is an item not generally available in the US,
quite rare in fact. Picture is available.
