Tiny Halogen Light Bulbs for Snap On Alignment Rack Toe Gauges, The Size of a 194, but Not a 194

I am still working on this Snap On alignment gauge project and need some light bulbs, but no idea what number they are.

They have the same end on them as a 194 bulb that might be found under a car dash. However the other end looks like a vintage Christmas tree bulb.

They are halogen and the light beam shines on the scale.

194 bulb in the 2nd photo next to what I need.

They are about 1.185" long and about .390" diameter.

Thanks in advance, and I do really appreciate it if you know what number I am looking for.
