You find this at science centers. It is not a light that is on a bike. It is like a exercise bike bike that is hooked up to something that when u get to the right speed the light bulb turns on. If you have a diagram that shows how this is built I would gladly appreciate it. I am building something that needs this information. Thank you if you can help me and thank if you can't. I appreciate the time you took to read this. BYE
