Abstract​

A warning light assembly is provided that includes a simple drive train for accomplishing an 180° or more oscillation of a light beam. By advantageously utilizing a speed-reduction mechanism, a transmission for converting rotary motion to oscillating motion and a coupling for multiplying the angle of oscillation, the drive provides an inexpensive and rugged enabling design the warning light assembly to oscillate a light beam through angles heretofore unattainable.

A drawing of Federal' Model 100 in an oscillating version. I never saw this in production. They did produce the MagnaBeam and the "V" version Sentry beacon in oscillating versions with this type of engineering

I guess theoretically the Federal Signal oscillating design translates pretty well from light to light. Sentry, Vector, MagnaBeam, Streethawk etc. But I agree I have never seen the Model 100 version as an actual light.
