Here’s a video to show the colorful lighting present on the Scranton Electric Building sign. In 2014, the sign was renovated and relit with colorful LED bulbs. The original lighting used incandescent bulbs, of course, and was first lit in the 1930’s. Scranton is called “The Electric City” because it was one of the first electrified cities. In fact, Scranton’s famous trolleys and streetcars were running as early as 1886.
