Hi, im considering buying a set of lights/lamps for my buggy build but dont what to go with traditional 7"round. Saw some realy nice PIAA lights but need to know the capacity of the alternator to handle voltage or amps. Do I go buy the amps required by each light fixture? thanks!

simple math here : watts = volts x amps your example: 60watt bulbs/12 volts = 5 amps each 120 watt bulbs/12volts=10amps each hope that helps MURZ

Ok and what is the output of the alternator? Is this measured at diferent revs or does it have a constant output with a regulator built in it? What amps or watts are u using in your lights? Where did the "watts" go in the formula, dont see it in the examples? or u mean 60 WATT bulbs/12 volts = 5 amps each

Sorry, brain fart. The post is correct now. I think a stock alt is around 50-55 amps. Now remember most system voltage is 13.3-13.8 volts when you are running so that brings your amp requirement down. MURZ

My glass buggy has 8 headlights total, they are rarley all on at the same time and I avoid night driving. ( deer ) It has a Delco that was built to put out 100 "true amps" whatever that means....Another thing to consider is running HID and or LED lighting. The less power consumed in generating electricity can be go back to throttle. They probably cost more than the normal halogen or sealed beam but the look cool and work well from what I have heard.
