Southern Autoflow
This 4 way was made by The
Southern Switch Co, of Shreveport, La. They were originally a maker
of electrical devices. Sometime in the early 1950's, they began
manufacturing traffic signal equipment, including 4-ways, called Autoflows.
This signal came with only 3 visors. They were cutaway style. Southern
Autoflow signals are not very common so I opted to replace the hard to
find original visors with modified Eagle tunnel visors. You can see what
this signal might have looked like with its original visors on
Signalfan's web site.

signal.
The bottom piece of this signal has mounting
holes for a controller that could be contained in the signal itself. This signal
did not come with one, so a Lights
To Go 4 way controller is installed there instead. Signalfan was lucky with
his Autoflow because it did come with the original controller. It was configured
so that the yellow light came on with the green light, then they both went off
when the red light came on. You can see an animation of his Autoflow sequencing
like this here.
