ABSTRACT:
A portable DC miniature lamp tester is formed by a generally rectangular translucent body formed from plastic material having an open socket therein for reception of the bayonet end of the lamp and a pair of conventional snap-tab connectors for cooperatively connecting the body to the terminals of a conventional 9-volt dry cell battery. The auxiliary lamp is illuminated when either the incandescent filament of the lamp under test or its shunt is still good and conducts current.
