I added some big KCs to the 420 for night riding. I think it looks like the ol Speed Buggy cartoon(for the ol farts that remember it). I think they are 100 watts apiece, could be 130s too. They are dim at idle but seem to brighten up decent when revved up. Total power out on a 350 is around 260-280 watts(what I remember), the engine uses some, tail/brake lights use some, instuments and back lighting use some. I think I may put a toggle switch on one light to see if it helps. We'll see how it works I guess. I don't want to melt any wires either. :shock:
