I see no need for a motorcycle light when plenty of excellent dynamo or USB charged lights exist and this seems like it would all be a heavy mess to schlep on a bike, You would probably need a motor just to haul the batteries and lights and fairings and whatnot.

When I was a kid, I mounted a full fairing from a Harley on an Araya road bike. It had 2 headlights, a stereo, and two speakers. It was hideous, but with a small 12 volt battery, the lights worked, and I could listen to music.

He mentioned that the bike has a 500-watt motor with a battery dedicated to that motor. It's probably not a light bike, and this lighting system probably doesn't make it terribly heavy given the likely use case.
