Lot of five vintage bubble light bulbs, plastic with glass tubes, not sure of the maker of these though I believe they're all of the same vintage, probably from the same set.
These have small socket bases (C6, I think) not like the newer reproduction bubble lights. I don't have a string that fits these, so I haven't tested them, and don't know if they light or bubble (one is empty of fluid, so that one I know doesn't bubble). Plastic looks good, no chips or cracks to the glass, metal fittings are a little tarnished.
