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, an alternating light, a flashing 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. 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.
