Federal Signal's 2nd Version Flash Ball was still a non rotating light like the Version 1, with some design changes.
It had the larger magnet, was available in halogen or incandescent bulb, and had a new reflector and socket design.
The reflector was still stationary. The bulb was flashed by a flasher for a directional warning.
These Flash Balls are even more rare than the Version 1 Flash Balls.
This light has a very different shaped anti vibration plate to allow room for the phono plug socket,
AND.... the part number looks to be EB 4, not FB 4!!!!!!!
I've never seen this before!
Another nice piece for my Fire Ball sub-collection!
Just found a FB-2 Fire Ball with interesting electronics inside. The electronics are between the motor leads and pos. and neg input. Not sure what it does. Any ideas?
I will post more pics after receiving the light.
Found this picture of the other Fire Ball that I've seen with these added electronics.
Can ANYBODY shed light on what these might do to the light?
The added electronics must do something to the motor function, as they are located in line between the power inlet, and the wires supplying power to the motor.
I have seen this before and I believe it was to prevent electrical noise of the motor running back into the vehicles' electrical system, suppression or isolation to prevent noise in the old two way radios. Possibly an old military spec if I recall..
