Warning light with accessory mirror

A warning light assembly comprising:

• a domed housing, a reflector and a lamp, the reflector and lamp being located within the housing such that the reflector is rotatable about a focal point of the reflector for rotating a beam of light emanating from the lamp located at the focal point,
• an attachment for mounting to the domed housing, including a surface for intercepting the beam of light over a portion of a full rotation;
• a set of first, second and third mirrors mounted to the attachment for reflecting the intercepted light in a predetermined direction, where each of the mirrors is positioned to reflect light at a different angle in the rotation of the beam such that 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 transportable warning light having an oscillating beam comprising in combination:

• a base section including means for securing the warning light to a surface;
• a reflector mounted in the base section to a gear for rotation about a axis containing a focal point of the reflector;
• a lamp mounted in the base section and at the focal point;
• a motor mounted in the base section for continuous rotation in a single direction and directly driving a warm gear comprising a worm and worm wheel so as to impart the continuous rotation to the worm wheel in a single direction;
• and
• means connecting the worm wheel to the gear supporting the reflector for translating the continuous rotation of the worm wheel to an oscillating movement for the gear and the reflector.

A transportable warning light providing a moving beam of light, the warning light comprising in combination:

• a base section including means for securing the warning light to a surface;
• a dome fitted over the base section;
• a printed circuit board mounted in the base section and having a ground plane printed circuit;
• a reflector mounted on the circuit board for rotation about an axis containing a focal point of the reflector;
• a lamp positioned at the focal point including a flange extending laterally with respect to a longitudinal axis of the lamp and providing a ground contact for the lamp;
• a mounting for the lamp secured to the circuit board and including a lamp socket and a conductive skirt around the socket, the skirt being in direct contact with the ground plane;
• and
• a clip for creating and maintaining a biased engagement between the flange of the lamp and the skirt.

An apparatus secured to a vehicle for providing to an observer of the vehicle a flashing visual warning signal such that the effectiveness of the warning signal for drawing the attention of the observer is optimized for the application of the vehicle and its environment, the apparatus comprising a base for mounting to a surface of the vehicle, an assembly supported by the base and including a reflector rotatable about a vertical axis and a lamp located substantially at the vertical axis, a motor supported by the base and coupled to the assembly by way of a gear mechanism for driving the reflector about the vertical axis in order to create the flashing visual warning signal, a cable for communicating a source of power to the motor and the lamp, a transparent dome fitted over the assembly and the motor and mated to the base, a switch interfacing the cable to the motor having at least two discrete outputs and an input and means for alternatively connecting one of the outputs to the input, wherein each of the outputs provides a different flash rate for the flashing visual warning signal by applying a voltage to the motor whose value is different from the value of the voltage provided by all other outputs, and at least one of the outputs of the switch including a resistor between and in series connection with the input of the switch and the motor, where the resistor has a value that is selected to provide a predetermined flash rate, which is optimized for the application and the environment of the vehicle.
