W.S. Darley Co. 4 way flashing traffic light. All red beacon was a D-132.
The original beacon design included a Time-O-Matic flash controller and lamp socket on the beacon floor. The lamp , usually 150 watts, illuminated on all four indications. Reflectors attached to the lenses amplified the light and reduced phantom illumination.
The four directions N, E, S, W are indicated by markings on the top of each side.
All 4 lenses are in good shape with no cracks. As you can see in picture the lights work.
There no accurate archives to date Darley signals by,but it is known that they were produced starting sometime in 1920. Darley signals are pretty hard to come by.
