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.
