Patent Images
1. A light bar comprisinga support for attachment to an object;
- a member rotatably mounted on the support for selective movement about a horizontal axis;
a lamp fixture;
means mounting the lamp fixture on the member for selective movement about a vertical axis;
means for selectively moving the member about the horizontal axis including a first electric motor and means connecting the first electric motor and the member;
means for selectively moving the lamp fixture about the vertical axis including a second electric motor carried by the member and means connecting the second electric motor and the lamp fixture; and
means for simultaneously energizing the first and second electric motors for simultaneously rotating the lamp fixture about the vertical axis and rotating the member about its horizontal axis.

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.
