This might sound silly or immature, but I was thinking about this. I used to watch a TV show called Tot's TV which was made in UK. In one episode I remember they showed a crew cleaning the streetlights. They were the typical bowl type British ones. Plus the cottage in the show had old rotary light switches which caught my eye as a kid.

I remember another show called the Reppies, which was filmed at the Tampa Theater, had an old mogul floor lamp with a mogul in middle and three lamps around it. I never knew what those were called or saw any others except here but it caught my attention. Also they showed the old electric lights in the theater pretty often.

Mr. Rogers (USA) had a traffic signal in his "home" that was shown on every episode.

That's true I do remember that, it was painted yellow.
