A light emitting diode (LED) warning signal light and double light bar includes a second light bar elevated with respect to a first light bar. Each of the first and second light bars includes a controller for generating a plurality of observable light signals. The controller may regulate the illumination of LED's to a desired pattern, sequence, and/or combination of simultaneous and/or individual light signals.
