I remember riding with cats that used these:



I was never much impressed. The lamps so often wiggled&squiggled around and uncomfortably dropped and/or pointed in an ineffective direction.

Today there are lighted pedals. AFAIK the too-clever-by-half Pedalite, with its internal belt-driven dynamo, is no more. The USB-charged RedShift lighted pedals are available.

You'd think in this age of miniature LED lights someone would offer an add-on pedal light. (Maybe it's just my Google foo but...) I can't find one, but you can add reflectors to most pedals, or purchase a functionally similar pedal that comes with built-in reflectors.
