Stovebolters, Whom can advise on a dual filament 1157 bulb replacement when converting from 6 volt to 12 volt? Pic shows original bulb. Thanks. V/r, Nick Cavallaro, Bel Air, MD
1157 is a dual filament 12 volt bulb. 1154 would be a 6 volt bulb. Maybe a PO started the 12v conversion already.

Sir, Wow! A quick response indeed! I will now see whether the 1157 bulb works without worrying whether hooking it up to a 12 volt battery wrecks it or not. Regarding whether conversion was initiated I would say no because the stoplight fixture was not on the door when I became 2nd owner. Also, it remains off the door while I restore it. Thanks Phil.

I can confirm an 1157 and its variants (2157, 3157, etc.) are a 12v bulb.
No turn signals on a '52 Burb. That tail light is strictly a running light/brake light only. Even the rare second door option for the barn door was no turn signal.
NJC With a 7-wire (like an original sgnal-stat chevy dealers put on )it takes only 3 wires to do brake lights,tail lights,turn signals. The turn signals and brake lights interchange. This would be with 2 12v 1157 bulbs as you said.
The 1952 Suburban, bone stock, whether clamshell or barn door, only had a single tail light. Dang near impossible to make turn signals out of that unless you added extra lights. The dual filament bulb, in the stock housing, acts as a tail light/license plate light and brake light. 1157's will work as tail light/brake - turn lights only if you add the extra light housings.
