A #47 bulb fits perfectly.  Its a single contact.  

According to the manual the socket has a built in resistor, I will need to pop off the top and measure the resistance to get an exact number since the schematics does not show the resistor only the socket. Let me find the resistance and let you know.

Daniel,

What size is the bayonet base? Is it small like a
#47 pilot lamp, or larger like a 12 auto backup bulb?
One contact or two?

Is there an external series resistor (maybe 100K)
or is it expected to be in the bulb?

My thought is, given the proper base and an NE2H, one
could improvise a bulb.

If I have the parts, I would be glad to do it for you.

Good Morning,

I have a TT-192A which is the compact reperf.  I am in need of a tape out bulb its is listed at a 115v Neon bayonet.  The navy lists it as i925 but I unfortunately can’t find a reference for that anywhere.

Does anyone have any insight to a replacement part number?

Thanks,
Daniel
