Abstract

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.

Claims

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

a) a first light support having a front side with a first visible exterior surface, and a second light support positioned above said first light support, said second light support having a front side with a second visible exterior surface;

b) a plurality of light emitting diodes arranged about and attached to the first visible exterior surface and to the second visible exterior surface; and

c) a controller in electric communication with the light emitting diodes, the controller constructed and arranged to activate the light emitting diodes thereby producing more than two different types of visually distinct warning light signals, the light emitting diodes receiving power from a power source.

2. The multiple warning signal light according to claim 1, wherein the controller generates the more than two different types of visually distinct warning light signals in at least one combination.

3. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated in any combination.

4. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated simultaneously in any combination.

5. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated alternatively in any combination.

6. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated in any combination of two or more visually distinct warning light signals.

7. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated simultaneously in any combination of two or more visually distinct warning light signals.

8. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated alternatively in any combination of two or more visually distinct warning light signals.

9. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated in any combination of three or more visually distinct warning light signals.

10. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated alternatively in any combination of three or more visually distinct warning light signals

11. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated in a regular pattern.

12. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated in an intermitent pattern.

13. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated in an irregular pattern.

14. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated in a regular sequence.

15. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated in an intermittent sequence.

16. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated in an irregular sequence.

17. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated at regular intervals.

18. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated at intermittent intervals.

19. The multiple warning signal light of claim 2, wherein three or more visually distinct warning light signals are generated at irregular intervals.

20. The multiple warning signal light of claim 2, wherein at least two different types of visually distinct warning light signals are generated simultaneously.

21. The multiple warning signal light according to claim 20, wherein three or more visually distinct warning light signals are generated simultaneously in any combination of three or more visually distinct warning light signals.
