Little update. Made a larger Dia pulley and installed the matching Kubota regulator/rectifier and I get 13.5 volts at about 25 mph. I will put a sealed battery and make a wiring harness and I should be good to go. Just trying to do something unusual. Like was suggested, I may give the LED a try. I can buy H4 socket Led bulbs to put in my existing light choice.
The light bar came with an old set of Dick Cepeck lights. I may powder coat the cans and use them. They also take the H4.
I made the light bar so it could be installed/removed in a few min. I will be able to put the white Maire head light on easy.
