Which is the HI beam and which is the LO ? Red, white and black. Black is ground. Thanks for the help, GlenOh, almost ready to start up and take for a go-cart ride. But we got three inches of heavy snow this morning (very pretty, actually) and its still falling. And lots of salt everywhere Think I'll need monster truck snow tires to get my anticipated horsepower to the road. Was wondering if any of you guys, maybe up in Canada or the Northeast, have a set you aren't using . No, the shipping would be too much . Thanks anyways. Come on spring!
