Sure, lots of people do, but you've probably been looking in the wrong
place. In the States, with its toy-bike culture (okay, let's be
polite: in the States, where bikes are mainly upmarket yuppie image
statements rather than workaday tools), dynamo lights are a luxury and
correspondingly rare and expensive (except at Yellow Jersey
apparently). In European countries where a bike is a utility tool,
just like a car (I haven't even owned a car since 1992!), a dynamo
light is a necessity, in Germany even a legal requirement, and
correspondingly common.
Search for "Shimano hub dynamo" (with the quotation marks) and "SON
+dynamo" (without the quotation marks) and you'll soon find lots of
information. The Steven Scharfe site and the Myra Simon page already
referred to by someone else were influences on me when I took up night
riding.
A hub dynamo has to be built into a wheel. The smart thing is to buy a
readybuilt wheel from some supplier's overstock. The best place to do
it German e-bay. Got to ebay.de and search for "laufrad
+nabendynamo" (no quotation marks) and you'll find a collection of
wheels from about forty euro up with hb dynamos built in; you should
be able to land a good one in the States for under a hundred bucks.
Once you have a hub dynamo, it can be made to do other things rather
than just light your way. For instance, at
http://members.lycos.co.uk/fiultra/BICYCLE Trek Navigator L700 Smover.html
you can see a hub dynamo powering a computer and a stepper motor that
automatically changes the gears on one of my bikes, and operates
active electronic suspension besides. At a slightly lower level of
complication, it is commonplace in Europe to use hub dynamos with a
sensor-switch either built into the light or added on (Shimano NX-30,
I think) in a little black box containing a motion and light sensor,
to switch the lights on when the bike moves and it is dark, and switch
them off again when dawn breaks or you stop.
If you have the money, I recommend the BUMM Fly IQ front light in
combination with one of the BUMM D Toplight plus versions -- the plus
is either a battery or capacitor powered light that stays on when you
stop at a stop street. The German rear light has no flashing mode, so
I back mine up with a Cateye TL-LD1100 which I keep flashing day and
night. If you cannot fit or afford both rear lights, get only the
flashing one, as 0.6W constant rear lights get lost in urban clutter.
HTH.
