The little white blob between the filament looks like the fusible pellet they put in 6V, series-strung Christmas lights. The idea is that in a series string powered from 120Vac, if a 6V bulb burns out, the full 120V appears across the burned out one, fusing the pellet into a short circuit, the string relights with a slightly higher voltage across each remaining lamp...

Garden centers and hardware stores usually have replacement packs around the holidays, but they are relatively expensive. The cheapest way to get spares is buy a complete string at an after-Christmas sale and pull all of the bulbs.

If they are soldered into a board you could look up a similar screw in lamp of similar ratings (like xmas lights) and solder a couple of wires to it and use that in its place.

More and more incandescent Christmas ornaments have been replaced by LEDs each season.
Pretty soon there will be none available.
