The oldest pedestrian signals that saw widespread use were implemented by putting 8″ WAIT and WALK lenses into the same housings used for vehicular signals.
I didn’t buy a WAIT-WALK signal off the street, rather, I put one together with two spare Marbelite ca. 1950 8″ housings that I had on the shelf. I traded some spare lenses for the Kopp WAIT and WALK lenses.
For extra decorative touches, I’ve got two choices; either a Detroit-made repro cast aluminum finial as a topper, or a pair of repro Marbelite “fins” made for me by Dave Conrad in Baltimore.
