brendanm720, dunno. don't know how many amps the booster can supply or how many the lighter needs. maybe a good solution ifen i can't find a 6v unit. thought about moding the winding by shortening it a bit, but that doesn't seem to be that easy to do either. oh well, on to bigger and better things like rear axle seals and truck bed wood kits.
