Abstract
A mirror assembly for use with a warning light which has a reflector that is capable of rotating a beam of light emanating from a lamp located at its focal point. The mirror assembly comprises a first set of first, second and third mirrors mounted to the attachment for reflecting the intercepted light in a predetermined direction, where the reflections occur first from the first mirror, then from the second mirror and finally from the third mirror; and a port between the first and third mirrors for passing light to the second mirror such that the reflected beam from the second mirror is further from the focal point than the reflected beams from the first and third mirrors. A warning light is also provided which may be used either alone or in combination with the aforesaid mirror assembly. One embodiment of this light comprises a reflector and lamp mounted in a base wherein the reflector rotates about a focal point of the reflector; a manually operable mechanism mounted to the base section and having variable positions; and means responsive to the mechanism for rotating the reflector at different speeds when the mechanism is in different positions. The design of the aforesaid light also includes a provision for either directly manufacturing a warning light, or modifying an existing warning light, such that the beam of light is capable of rotating 360.degree. oscillating about the warning light. A printed circuit board may also be included in the warning light.
