As usual, I found this while I was looking at other things on the Intertubz. The Humphrey Gas Light.
I remember similar lights in old travel trailers when I was a kid. I don’t know what models were available back then, but today there are a variety of models, colors and accessories that should allow you to adapt these for just about any use. The immediate uses I see is for off-grid lighting or emergency lighting. If you were building or retrofitting a house or a building, it wouldn’t be much trouble to pipe in propane to various locations and install some of these for future use.
