Traffic Signal Collection

Other Signal Manufacturers

Here are some of the signals in the collection from some of the other historic manufacturers. Click on the links to go to descriptions and close-up photos of each signal.


Alusig and Durasig are progenies of the old Eagle Signal Co. Eagle signals evolved into Alusig aluminum signals and Durasig polycarbonate signals. The polycarbonate signals were less expensive and lighter, but the earlier models tended to get brittle when exposed to the elements for a long time. The collection includes a 3-section Alusig, a 5-section Durasig and a Durasig pedestrian head.


Econolite actually dates back to 1933 but they were primarily sellers and installers of GE signals until 1957 when Econolite bought out the GE line. Econolite added round "bullseye" 12-inch heads to the original GE designs, and they are also known for their popular exposed tube neon WAIT - WALK and DON'T WALK - WALK pedestrian signals. The collection includes a 12-8-8 head, a double 8-inch fire signal head, a WAIT-WALK neon head and a DON'T WALK-WALK neon head.


Harrington Seaberg of Moline, IL, was an early manufacturer of traffic signals. The original company was named Harrington Machine and Electric Company. By 1922 they were taking orders from major cities for traffic signal equipment, and in 1923 the company was renamed Harrington-Seaberg after its original founders. In 1929 Harrington-Seaberg was bought out by Gamewell. Gamewell also owned Eagle Signal so the Harrington-Seaberg line was dropped. The collection includes one Harrington-Seaberg fixed 4-way signal from the mid 1920s.


Highway Signal and Sign was a spin-off of the old Horni Manufacturing Co. HS&S signals carried many characteristics of the old Horni signals as well as Marbelite (the company that bought Horni.) It is theorized that the old owners of Horni sold signals through the HS&S brand to fulfill contract obligations and many of the parts were probably made by Marbelite.


LFE (the Laboratory for Electronics) produced signals from the 1950s to the 1980s. They bought out inventor Charles Adler, Jr.'s Automatic Signal Co. that he founded in 1922. The collection includes a 12-8-8 traffic signal, a 4 section "yellow trap" signal, a 5 section "dog house" signal and a 12" round Canadian style pedestrian head.


McCain Traffic Supply produced both aluminum and polycarbonate heads. These signals were rather utilitarian in their designs. The collection includes a 12-12-12 traffic signal, an 8-8-8 traffic signal and an LED pedestrian head.


Plessey is a British manufacturer that made the classic Plessey Tin Lanterns seen all about the United Kingdom. The original Plesseys were originally painted black and white until the 1960s when the standards changed for signals to be painted all black. The collection has what is known as the "riveted" model as the face plate is riveted to the body.


Signal Service Corporation was the successor to the old American Gas Accumulator (AGA) line of traffic signals. SSC produced elegant looking signals until shortly after World War II, when the line was taken over by Marbelite. The collection includes an SSC fixed 4-way signal and a fixed 3-way beacon with an offset angle adapter.

More signals will be added as they are restored.
