Street Light Technical Information Willis Lamm   STREET LIGHTS: Patents from 1932 through 1933

Patents are an effective way to understand the development of street lighting in the United States. In this section I have posted patents as I located them. (Early patents are difficult to locate as they were not cross-indexed.) All patents are listed in order of their filing dates. Click on the patent number or thumbnail to view the entire patent.

Even though the economy was in a rut, inventors still continued to turn out dozens of street lighting improvements.
