Rear window Model A stop light, 6V will not work w/ 12V & !2V will not work w/6V.

Model A stop light is what I have, thanks, question answered. When I started my project one of the first things I needed to do was to get the electrics sorted. The generator was shot and the repair quote was dearer than a new alternator so I went for a 6v, now I wish I had gone for 12v. I was thinking about changing but adding up all the bits needed for just doing it for the sake of it, I`ll leave it as is............................
