Night light bulb and socket

The sockets can be purchased at hardware, home improvement stores. Most of them are white, but this is a black one I painted white (not a very good paint job). I think I ended up having enough white ones that I did not have to use this one in the dollhouse. The sockets are wired together from room to room with stereo speaker wire. Lamp wire can be used, but it is larger than the stereo speaker wire and I like the smaller wire best.
