Abstract

A self leveling warning light for vehicles employing a light assembly that is pivotedly secured to an inner surface of a vehicle window by a mounting base suction cup. The light assembly has a plurality of LEDs whose intensity is amplified by a reflector and focused by an optical lens providing light emission in distances exceeding one mile with minimal battery drain. A control circuit having a power source is mounted within said light assembly and electrically coupled to the LEDs, the control circuit controlling four red LEDs separated by a centrally located yellow LED, the four red LEDs alternate on and off at sync rate of approximately 500 ms and the yellow LED turns on for about 750 ms and off for about 1 second. The light assembly maintaining directional pointing of the LEDs in a horizontal plane when the mounting base is moved between vertical and horizontal orientations by gravity weighting of the light assembly.

Claims (21)

1. A self leveling warning light for vehicles comprising:

a mounting base having a suction cup for releasably securing to the inner surface of a vehicle window;

a light assembly defined by an upper end and a lower end with a plurality of LEDs positioned therebetween, said upper end of said light assembly pivotedly attached to said mounting base;

a control circuit having a power source mounted within said light assembly and electrically coupled to said LEDs; and

a means for maintaining directional pointing of said LEDs in a horizontal plane when said mounting base is moved between vertical and horizontal orientations, wherein said means for maintaining directional pointing include positioning of batteries along said lower end of said light assembly, said batteries having a weight that causes said lower end to be positioned below said upper end when said mounting base is rotated.

2. The self leveling warning light for vehicles according to claim 1 wherein said light assembly includes a transparent lens cover to protect said LEDs from misalignment.

3. The self leveling warning light for vehicles according to claim 1 wherein said light assembly includes an optical lens for enhancement of directional lighting.

4. The self leveling warning light for vehicles according to claim 1 wherein said light assembly includes a reflector for enhancement of directional lighting.

5. The self leveling warning light for vehicles according to claim 1 wherein said control circuit operates said LEDs in a blinking pattern.

6. The self leveling warning light for vehicles according to claim 5 wherein said control circuit operates said LEDs as a strobe.

7. The self leveling warning light for vehicles according to claim 5 wherein said blinking pattern consists of four red LEDs separated by a centrally located yellow LED, said four red LEDs alternate on and off out at a sync rate of approximately 500 ms and said yellow LED turns on for about 750 ms and off for about 1 second.

8. The self leveling warning light for vehicles according to claim 1 wherein said LED's are positioned on the same side as said mounting base.

9. A self leveling warning light for vehicles comprising:

a mounting base having a suction cup for releasably securing said mounting base to the inner surface of a vehicle window;

a light assembly defined by an upper end and a lower end with a plurality of LEDs positioned therebetween, said upper end of said light assembly pivotedly attached to said mounting base;

a reflector placed adjacent said LED's for enhancement of directional lighting;

an optical lens positioned over said LED's for enhancement of directional lights;

a control circuit having a power source mounted within said light assembly and electrically coupled to said LEDs; and

a means for maintaining directional pointing of said LEDs in a horizontal plane when said mounting base is moved between vertical and horizontal orientations, wherein said means for maintaining directional pointing include positioning of batteries along said lower end of said light assembly, said batteries have a weight that causes said lower end to be positioned below said upper end when said mounting base is rotated.

10. The self leveling warning light for vehicles according to claim 9 wherein said LEDs consists of four red LEDs separated by a centrally located yellow LED, said four red LEDs alternate on and off at sync rate of approximately 500 ms and said yellow LED turns on for about 750 ms and off for about 1 second.

11. The self leveling warning light for vehicles according to claim 9 wherein said control circuit operates said LEDs as a strobe.
