Switchboard Indicator Lamps
I need some to restore some old telco equipment. The bulbs are a slide base,
24V 2W incandescent, similar to these: https://www.grainger.com/product/LUM...r-24PSB-21U505 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? -- Paul Hovnanian ------------------------------------------------------------------ If it wasn't for physics and law enforcement, I would be unstoppable! |

I'm in the process of bulk disposal of my old shop stock, as you can see from the last update date http://www.diverse.ip3.co.uk/compfull.htm in the UK though, as in the pic you refereed to. IIRC they came from an aircraft repair facility , so maybe used in cockpits also |

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!
