Abstract
Abstract A light bar, primarily for a vehicle, comprises a support extending transversely across the top of the vehicle. Attached to the support are one or more lamps which are mounted for selective rotary movement about a horizontal axis transverse to the vehicle and a vertical axis. By the manipulation of suitable controls inside the vehicle, or by manipulation of a remote control actuator, the driver is capable of aiming the light at a desired object or scanning a desired region.
