Abstract

A light emitting diode (LED) warning signal light, the warning signal light comprising an array of light sources configured on a light support and in electrical communication with a controller and a power supply, battery, or other electrical source. The warning signal light provides various colored light signals for independent use or use by an emergency vehicle. These light signals may include a stationary light, strobe light, revolving light, and an oscillating light. Additionally, the warning signal light may be capable of displaying symbols, reverse characters, or arrows. Preferably, rotating and oscillating light signals are produced by sequentially illuminating columns of LED'"'"'s on a stationary light support. However, the warning signal light may also be rotated or oscillated via mechanical means. The warning signal light may also be transportable for easy connection to a stand such as a tripod for electrical connection to a power supply as a stand-alone warning signal.

Claims

1. A multiple warning signal light for use with a motorized vehicle, the multiple warning signal light comprising:

a) a light bar;

b) a plurality of light emitting diodes arranged about and attached to the light bar; and

c) at least one light signal regulating device in electric communication with the light emitting diodes, the at least one light signal regulating device constructed and arranged to activate the light emitting diodes thereby producing at least two different visually distinct warning light signals, the at least one light signal regulating device further constructed and arranged to produce the at least two different visually distinct warning light signals simultaneously, said light emitting diodes receiving power from a power source.

2. The multiple warning signal light of claim 1, wherein the plurality of light emitting diodes are grouped into a plurality of sector'"'"'s.

3. The multiple warning signal light of claim 1, said light bar comprising a first side and a second side.
