Default Re: 6v custom headlight rig. need someone smarter than me

Hook a rectifier diode to the white wire and use that to trickle charge the battery when the headlight is not being used. That might be enough if you only use the headlight occasionally and you do enough driving during the day to recharge the battery. If you use that large headlight often, you will have to have some other method to keep the battery charged.
