Re: Running Lights
If they are 12v, you will need a 12v battery. I would most definitely fuse the positive side. No need for a relay. The engine puts out closer to 6v and 3 watts, so it will not run the 12v lights. See what the wattage draw is, they you will know what size battery you need. I have full turn signals, turn, brake and headlight. I use a 7ah 12 volt rechargeable and it will run the lights for hours, but I only have a 7 watt headlight that I use for a daytime running light, I do not ride at night. If I did, I would want at least a 20watt headlight (35 is better), and the battery would still run the lights for over a 2 hours.
