Exactly, "bike head lamps" are common, I'm talking about real "headlights" in a vehicular sense. A shaped beam with cutoff, where the emitter or lamp isn't projecting directly, and has actual high and low beams rather than just multiple power levels with some sort of defuser.
The only two I'm aware of are the Specialized flux, and Phillips Activeride.
