One of the first traffic lights I ever bought was this circa 1950 Crouse-Hinds Type DT. These were manufactured over a relatively long period. Originally known as the “Type D” in the 1930s and ’40s, then as the “Type DT” in the early to mid 1950s, these are very popular with collectors, just as they once were with transportation departments across the country.
The D/DT models have an open sectional design that is capped off at the ends with finned plates, and is all held together with a pair of tie rods. They came with either removable sheet metal visors or solid cast visors integrated with the doors, as this one has. The original lenses in my signal were Crouse-Hinds “small-bead smiley” pattern lenses. I replaced the smileys with a set of (older) Crouse-Hinds STOP, CAUTION and GO command lenses. I also added a reproduction finial made of a plastic/resin material. The brushed-on yellow paint is in very nice shape, so I did not bother repainting the light.
