I was at Walmart today. Bought a headlight/taillight set. Taillight runs on 2 AAA batteries. The headlight runs on 4 AA batteries. Now, I agree that littles batteries are not the idea power source for a motor biker, but I can take them back in a day or 2 if I don't want them. I've attached some pictures. But my question is, can I run them off my white wire? I don't want to just try it without your advice cause if I screw up.... The headlight has a normal light setting, a LED (blue) and a flasher setting. The taillight is on steady or there is like 3 differant flasher settings.
