I need help identifying the proper nomenclature for sealed beam bulbs

would like to convert from the old hard to find six volt screw post
batteries to the newer twelve volt type. I just don't know the proper
nomenclature for a twelve volt sealed beam lamp that is three and a
half inches across and is connected by screw terminals on the back of
the lamp.

if you don't get an answer here, poke around donsbulbs.com; you won't
get the answer quickly but a little searching can be helpful. That's
how I eventually figured out how to get the correct bulbs for my car
when converting from 6V to 12V and the equivalent wasn't listed in Randy
Rundle's otherwise very helpful book. (front signal lights were an odd
bulb; similar to a 1034 but without the offset pins, as back in 1955
turn signals were optional so the lamp assemblies were built all with a
straight-pin socket, turn signals were added by replacing the single
contact assembly with a dual one.)
