Re: 12 volt fog lamp as headlight
try this one...use a 12v 5ah gel cell battery. you can find them on ebay. about $15 shipped. use a 12v 1156 socket gm tail light. and dont`t forget to buy a charger. in total, it cost less than the rest of the idea`s mentioned. you can mount the battery in any direction and use led bulbs. my friend got 5-7hours of run time on a single charge,with very min voltage drop...he runs serveral lights on the bike. head,tail and turn signals. all bulbs are led...
