I think the other members have answered your question, but nobody has asked you WHY. So, I will. Why do you want to know if the DOT has approved any motorcycle headlights?
Because I think that depending on how you answer, the discussion could go in a couple of different directions. Does this have anything to do with your electric-pedal hybrid bikes? Or do you also have a motorcycle? If yes, what kind? What are you trying to accomplish? etc. etc.
Might lead nowhere, but still be nice to know where you're coming from, neighbor.
