Abstract

A light emitting diode (LED) warning signal light, the warning signal light comprising a plurality of light sources constructed and arranged with a reflector or cullminator, the LED light source being 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 strobe light, revolving light, an alternating light, a flashing light, a modulated light, a pulsating light, an oscillating light or any combination thereof. Additionally, the warning signal light may be capable of displaying symbols, reverse characters, or arrows. The controller may further be adapted to regulate or modulate the power intensity exposed to the illuminated LED'"'"'s to create a variable intensity light signal.
