ok so i would like to put a bigger light on my bike put i have read that some of the motors are putting out ac. how do you check and see if it is or isnt ac or dc. i have a small battery that came out of a spot light that i was planing on hooking up to the white wire then to lights. right now i am running a genarator light kit off of the white wire. the front puts off enough light that others can see me but i would like more as i drive home at 11:30 pm every night. i have read that you could put a zener diode and a resitor in line to make a regulator put what size's are they. i have a small meter if someone could tell me what to check for then i could build something that would work for me.
