Now that I got this working I want to upgrade to nihm batteries and a higher aH. Has anyone used one switch to power two lights? Like One setting for one light, another for the other, then a 3rd position for both lights at once and finally a 4th position for off? Would it just be easier to use 2 switches?

For you guys that have multiple headlights and taillights run off the same battery, how many switches do you have?

Does anyone have a voltage regulator?

Can anyone recommend any good books for someone starting out with this type of thing?
