An incandescent radial wave street light strung on a span wire (a rather commonplace practice for decades through the 1950s) with a pretty big lightbulb within it illuminated one of this Washington State business district's intersections. Electric utility distribution lines are seen along the right with all kinds of cool store signs, etc., throughout ;-)

Added note: A lot of series street lighting circuits in earlier years operated with inherent high open-circuit voltage. Strain insulators as seen were often spliced within each supporting guy-wire cable to prevent such dangerous electric continuity to their deadends and structures in the event of a series-circuit open-circuit fault.
