Ok first off let me start by saying I'm brand new here but I've been lurking for a while and have found some good info. I have a 2002 yz125 that I recently was able to register as a street legal bike. I'm trying to retrofit it with lighting for riding at night. I was planning on using the tusk led kit with the led taillight blinkers etc (don't draw a whole lot of power) and i would like to use 2 10w led lights side x side for a headlight. What I'm looking for is advice on what kind of battery I will be able to fit in the air box that will give me maximum usage time of the lights. I thought about going the upgraded stator route but it seems complicated and a stator for my bike isn't easy to come by. If anyone could lend some advice that would be much appreciated. I'm not very good when it comes to knowledge about batteries themselves or what I would need. I'm looking to get at least a few hours of lighting time if possible. Thanks for any help!
