I need some to restore some old telco equipment. The bulbs are a slide

24V 2W incandescent, similar to these:

but longer. The above lamps are 1-7/64" long (28mm). The lamps I need to
replace measure 43mm.

These things are OLD. The above Grainger bulb has a plastic wedge-shaped
base. The base of the lamps in this old equipment are wood.

Any ideas on sources or even the proper size/type name?


T-2 bulbs measure 1-11/16" in total length. You are looking for 24C1
Telephone and Indicator bulbs according to my old light bulb spec guide.
They are rated as 0.06 - 085A, 1900 Footcandles, average cold resistance
33R, hours life = 5000.

I might have those in my ancient parts stock if you can't find them
elsewhere.

At least you know what you are looking for now!
