Abstract: A modular rotatable warning light incorporates a standardized shaft, rotatable sub-assembly, motor and worm gear to form the mechanical core of the assembly. The rotatable sub-assembly includes a rotatable reflector mount supported by two axially spaced bearings for rotation around a hub. The axially spaced bearings significantly improve the function and service life of the rotatable warning light. The standardized parts are combined with a selected base plate, lamp holder, lamp and reflector to produce a modular rotatable warning light having a specified overall configuration. The efficiency of production and maintenance of various rotatable warning light configurations is improved by reducing engineering, production, maintenance and inventory costs.
