I guess my desires are different, but all I want is a simple, drop-in LED headlight bulb with a 10mm edison screw base and a built-in standlight circuit. I don't really care if it's super-bright, and I don't care about the beam shape. I just want my vintage dyno lights to work when I stop pedaling, with minimal fuss.

Also, while you're at it, can you make a dyno headlight/taillight set for under $40 for both pieces, with standlights?
