My 1948 M5 has original NACO tail lights that use a standard 6 volt 1154 bulb described as a Ba15d base, dual filament, S8 glass size. I have another pair of NACO tail lights that I will install on an antique utility trailer that I am refurbishing that needs to be 12 volt. I've looked at dozens of websites but have found nothing that has the bi-pin configuration of the original but is 12 volt dual element for tail light/stop light use. Does anybody know of a lamp with the vintage bi-pin Ba15d socket that is dual element at 12 volts?
