Abstract
A scuba or snorkel device with a circuit will turn on a light (preferably an LED) one or more times over a timed flash interval but will respond to a further closure of said switch during the flash interval. A circuit is provided to prevent response to such switch if two probes do not sense that the probe is in water. The circuit preferably will time a longer interval and turn on the light if the motion responsive switch is not actuated over the longer interval.
Claims21
Underwater light assembly for swimmers comprising:
- a body having:
- a power source;
- a circuit including circuit timing means for timing a flash interval;
- a motion responsive switch responsive to movement of said body to perform alternate transitions between connected and disconnected states where it respectively connects and does not connect said battery to said circuit;
- at least one light source having ON and OFF states, said circuit being responsive to the switch transition from disconnected to connected states connect said light to said circuit causing it to turn on, then disconnect it, after said flash interval determined by said circuit timing means;
- a portion of said body between said source and the body's exterior being adapted to transmit light from said light source, from said body.
