Bulbs for dash pad switches?

[moynistan]

I am overhauling switches on my 4V K100 (91).  The 4 way flasher switch looks as though it has leads going to the empty socket under the hazard symbol.  Is there a bulb for this spot and if so what type, number, etc.?  Thanks in advance, and apologies if this is in the Lieberry, I searched with no luck.

The early hazard switches did have three wires to them and a little bulb inside that the flasher relay blinked with the turn signals.  It was part of the switch and not a separate part.

If you're going to fiddle with installing a light in there then I'd go with an LED:

Maybe someday when I don't have 15 other loose ends...thanks
