Light Bulbs for Oldies
 

Anyone know where to find a six volt 5" sealed beam bulb?

Try Tractor Supply or other "farm-oriented" store. They carry a pretty wide variety of sealed beams and bulbs that fit older bikes.

Thanks, I'll give it a shot

Good post up jeff, another option is of the older rigs. My '55 fairlane is 6 volt as well, so checking out older rod sites may help find a 6 volt source.
