For helping keep this great

Again, thanks! | | | | Joined: Jan 2015 Posts: 125 Shop Shark | | Shop Shark Joined: Jan 2015 Posts: 125 | I have a 49 chevy 3100 and it's been converted to 12 volt to the point of running etc and fuse box. Does the bulb fittings have to be changed in order to run 12 volt bulbs or head lights? Does anybody have a chart for 6v to 12v bulbs and headlights?
Thanks in advance,
Paul

What about headlights? I also seen where the fittings take both 6 and 12 volt bulbs so im good there.

#6014 (50amp low/60amp hi). The 12v halogen bulb is #6024.
