ABSTRACT:
An emergency vehicle light bar assembly employs first and second connected substantially horizontal elongated frames mounted transversely across the upper surface of an emergency vehicle. The connecting assembly is such that the second frame may be substantially continuously vertically displaced while maintaining parallel relationship of the frames so that the emergency indicating equipment fixed atop the second frame maintains its operational attitude regardless of the elevation to which the second frame is raised. Reciprocable operation of the connecting assembly may be accomplished by electric, hydraulic, pneumatic or manual drive systems.
