Abstract

A warning light assembly for a watercraft or land vehicle includes a selectively activatable light for mounting to the watercraft or vehicle such that the light is clearly visible to nearby operators/drivers. There is a power source for being carried by the watercraft/vehicle. The light is operatively connected to the power source through a switch that is alternatable between open and closed states. At least one mechanism is provided for sensing when the watercraft/vehicle is decelerating. A control device is responsive to the sensing mechanism for closing the switch only when the watercraft/vehicle decelerates in a longitudinal direction and simultaneously there is no change in acceleration in a transverse direction. This causes the light to activate so that a deceleration warning is provided to nearby persons.

Claims

1. A warning light assembly for a watercraft, said assembly comprising:

a selectively activatable light for mounting to the watercraft such that said light is clearly visible to persons in nearby watercraft;

a power source for being carried by the watercraft, said light being operatively connected to said power source through a switch that is alternatable between open and closed states;

a sensor that detects changes in acceleration of the watercraft;

a controller responsive to the sensor, which controller closes said switch to operate said light in response to deceleration of the watercraft; and

a flasher switch attached to the watercraft and operatively connected to said controller, said flasher switch being selectively actuated by an operator of the watercraft and said controller being responsive to actuation of said flasher switch for closing and opening said light switch intermittently to flash said light on and off repeatedly and generate an emergency warning signal.

2. The assembly of claim 1 in which said light is mountable to a rearwardly exposed section of the watercraft.

3. The assembly of claim 1 in which said light includes a plurality of LEDs.

4. The assembly of claim 1 in which said switch includes an electronic switch.

5. The assembly of claim 1 in which said power source includes a battery.

6. The assembly of claim 4 in which said control means includes a microprocessor for opening and closing said switch in response to receiving a respective predetermined signal input from said means for sensing.

7. The assembly of claim 1 in which said means for sensing includes an accelerometer for measuring the g forces exerted upon the watercraft.

8. A warning light assembly for a vehicle, said assembly comprising:

a selectively activatable light for mounting to the vehicle such that said light is clearly visible to persons in nearby vehicles;

a power source for being carried by the vehicle, said light being operatively connected to said power source through a switch that is alternatable between open and closed states;

a sensor that detects changes in acceleration of the vehicle;

a controller responsive to the sensor, which controller closes said switch to operate said light in response to deceleration of the vehicle in a forward direction of travel; and

a flasher switch attached to the vehicle and operatively connected to said controller, said flasher switch being actuated by an operator of the vehicle and said controller being responsive to actuation of said flasher switch for closing and opening said light switch intermittently to flash said light on and off repeatedly and generate an emergency warning signal.

9. The assembly of claim 8 in which said means for sensing includes a multiple axis accelerometer that senses the changes in acceleration, said means for controlling including an electronic switch and a microprocessor that is programmed for closing said switch to activate said light when the vehicle decelerates along said primary axis while simultaneously there is no sensed change in acceleration of the vehicle along the secondary axis.

10. A warning light assembly for a personal watercraft, said assembly comprising:

a selectively activatable light for mounting to the personal watercraft such that said light is clearly visible to persons in nearby watercraft;

a power source for being carried by the watercraft;

a sensor that detects changes in acceleration of the watercraft; and

a deceleration control circuit responsive to said sensor, which deceleration control circuit actuates said light in response to deceleration of the personal watercraft in a forward direction of travel; and

11. The assembly of claim 10 further including a flasher switch mounted to the watercraft and operatively connected to said control circuit, said flasher switch being selectively actuated by an operator of the watercraft and said control circuit being responsive to actuation of said flasher switch for intermittently operating said warning light to flash on and off.

12. The assembly of claim 10 in which said light is amber.
