Southern Switch & Signal Co. of Shreveport, LA, produced a number of brands of traffic signals. Many of these manufacturers offered low cost 4-way signals from the late 1920s up into the 1960s that were ideal for small towns. Many signals had internal timing controls that weren't very sophisticated but were ideal for smaller, "stand alone" intersections. One company, Teeco Safety, still sells 4-way signals internally controlled or externally controlled, for use in replacing classic signals in historic districts. |

1930 Autoflow
| 1930 trade ads show Southern Autoflow's standard hinged door signal. Since older style Autoflow porthole style signals have also been found, it is likely that the portholes were first made in the late 1920s and may have continued into the 1930s for customers that still preferred the original porthole design. |

Some early timing sequences were not real accurate. Yellow displays primarily meant, "Attention! The light is changing!" Ergo there wasn't such concern that lamps lit and went dark at precisely the right instant. You can view a video of the
Autoflow's sequence to see what I mean.
