Original unused boxes of ten Westinghouse Mazda #1491 automobile lamps (.8 amps, 2.4 volts) for the antique automobilia collector or antique car owner. Each original orange and black Westinghouse Mazda cardboard box (6 1/2" long x 2 1/2" deep x 2 1/2" high) holds ten unused bulbs in a cardboard insert. The end of the box indicates that these are G8 bulbs with DC bayonet base.
One of our friends believes that these are the regulator bulb for the old Harley motorcycles with a generator. It's the generator light that is also a ballast resistor for the regulator. Thanks Don.
