thanks. I remembered the difference between Auf und Zu, opened
the lamp, and the bulb looks burned out. I'm really surprised that it
burned out relatively quickly (I doubt I have more than 20 hours
on the bulb), but I suppose that can happen. I'll figure out where
to buy replacement bulbs.
thanks

Sounds like a burned out bulb.  Put a spare in and see what happens.

If you have a continuity tester or multitester, use it to see if your  
bulb has a broken filament.

It takes 6V to light up the light, an AA battery putts out 1.5V.  You  
can probably tell by eye, look for a break in the filament.  You  
might need a magnifying glass.

Headlight bulbs burn out.  They cost about $5 or so for replacements  
and can be replaced in about 60 seconds.  I carry a couple of spares  
with me.  FWIW I have never blown out a bulb with my hub generator  
but have blown them out with a tire-driven generator.  I assume the  
latter over-volts the bulb at high speeds and burns them out quicker.
