Marv,
That is a 24 v 40mA lamp that the old spec called for. Also called a grain
of wheat lamp. Usually has a pair of insulated wire leads attached to the
bulb with a bit of heat shrink at the junction, bulb to wires. 3mm = 1/8"
dia bulb.
the model railroad guys use them but sometime they go to lower voltage.
Telephones used to have them here (South Africa) but those were usually just
the bulb with the terminals folded alongside to be able to plug into a
socket. Trucks sometimes have them in the instrument panel.
Good hunting,
Tony

Radio Shack use to carry them. But once they put the component competitors

as Layfayette and Allied out of business, they dumbed down their sales force

eliminated 90% of their components, focusing on high end system sales
leaving
everyone who experiments high and dry.
Try an industrial distributor in your area, such as Newark, Indusrial
Electronics, Shields Electronics, National Electronics and so forth.

Marshall, Thank you for the help. It may be a 24 volt lamp, but I have
no way of knowing the current rating. I will start my search looking for a
lamp designated as "grain of wheat", and hope I connect.
Best regards,
