ABSTRACT:
A modular-type lightbar assembly has an elongated base having a bottom panel and a pair of oblique integrally extending front and rear sides. Lens elements are mounted to the base and a cover by lock and groove-type connections. Warning beacon units are mounted to platforms supported on base. The beacon units rotate for sequentially directing light through the front and rear lens elements. The beacon units have an efficient integral base which mounts the rotating beacon and a brush assembly for the motor. An electronic controller is employed to apply a pulse width modulated current to the beacon motor so that a fast and slow motor speed may be selected.
