Lighting is the $64 question on everyones minds. The info available is plentifull. What I have been able too find out for myself... Take it with a grain of salt..
The white wire works fine for a constant tail light made of three led lights. two 5mm 1.8v, and one 10mm 2.4v in the middle wired + to -, giving you a 6v taillight. From what I have read, the magneto wont last as long with the drain of a headlight of any worth.. I know that statement will upset many people, but keep in mind, I ride in the open desert on unlit roads where darkness takes on a whole new meening.. And I beat my throttle like a red headed step child at K mart. I need to really see whats in front of me. I almost hit a big horn sheep once. And the argument of wide view or tight beam is another issue.. I have not seen Norms light, I have heard good things. But for my personal level of satisfaction. Nothing beats a good 12v battery and generator combo. I hope to scrape up the cash for one soon. A nice 12v generator with a dry cell backup would be great. I am now running twin 7.2v flashlight bulbs in 1895 light housing with convex lense. Lasts about 1.5hrs. charges in 1hr. and its easy to carry up to 3 batterys. bulbs are staggered. one close to lense up high, the other way in back center. it gives me both a beam, and a wide view. Not the greatest still, but better than anything I have seen so far that runs on the white wire. I have also had good results with 10mm led lights. Its just my opinion
