Traffic Signals Incorporated

Corporate History and Overview

Traffic Signals Inc. (TSI) was the short-lived successor of Southern Signals. TSI formed in 1960 when Southern Signals changed the name of Southern Signals to Traffic Signals Inc. They were bought by Singer in 1970.

Traffic Signals

TSI based their 4-ways off of Sargent Sowell's design. All of their signals used Dzus fasteners for latches and the visor collar was wider than most signals.

Four Ways

TSI only made one model of 4-way. They had the option of having an internal controller.

TSI made 8 inch and 12 inch single-face signals. The main difference between the two is that the 12 inch ones have two latches instead of one.
