Simplex 2903 Light Bulbs and Sockets

Hi all,

I’m going to be getting a lot with some Simplex 2903 light plates in a few days. There is a 2903-9102 plate that is missing the light bulb and socket. Does anyone here know what type of bulbs I’ll need, or a good substitute? I’ll also need to know what type of socket I’ll need. Thanks for your help!

Here is what I have found so far.

I think the 24 volt incandescent type used a type 1829 miniature lamp.

Thank you! Luckily those 1829 bulbs are easy to find online!
