Abstract

When a marine engine is on, automatic daytime running lights shall be illuminated. For example, white lights situated in the bow area of the boat would increase visibility of a boat to others, for safety purposes. The same lights or lights generally in the same area, at dusk and/or at night shall manually or automatically transition to red/green navigation lights.

Claims

1. A method for increasing visibility of a motorboat having an operating engine in the vicinity of other boats, comprising the steps of:

providing a light emitting safety lighting device positioned in the bow area of the motorboat to controllably cast safety light in an outward direction from the motorboat;

connecting the safety lighting device with a power source, the engine of the motorboat, and a circuit; and

providing a switch in the circuit situated so at automatically energize and illuminate the light emitting safety lighting device with the power source in response to operation of the engine of the motorboat, whereby cast safety light from the safety lighting device increases visibility of the motorboat to other boats in the vicinity of the motorboat whenever the engine thereof is operating, for safety purposes.

2. A method as in claim 1, wherein said cast safety light comprises white light.

3. A method as in claim 1, wherein said safety lighting device comprises a pair of white lights on either side of the motorboat bow.

4. A method as in claim 3, wherein said safety lighting device further comprises an additional pair of respectively colored lights on either side of the motorboat bow.

5. A method as in claim 4, further including the step of energizing the pair of white lights whenever ambient light conditions around the motorboat indicate daylight conditions, while deenergizing the pair of respectively colored lights.

6. A method as in claim 4, further including the step of energizing the pair of respectively colored lights whenever ambient light conditions around the motorboat indicate other than daylight conditions, while deenergizing the pair of white lights.

7. A method as in claim 1, wherein:

the safety lighting device comprises a white light on the motorboat bow, and a colored light on the motorboat bow; and

said method further includes energizing only the white light whenever ambient light conditions around the motorboat indicate daylight conditions, and energizing only the colored light whenever ambient light conditions around the motorboat indicate other than daylight conditions.

8. A method as in claim 7, wherein:

the white light comprises a pair of white lights on either side of the motorboat bow; and

the colored light comprises a pair of respective red and green lights on respective sides of either side of the motorboat bow.

9. A method as in claim 8, wherein the red and green lights are respectively on respective port and starboard sides of the motorboat bow.

10. A method as in claim 8, wherein the respective red and green lights comprise non-colored lights which are mounted under respective red and green colored covers, so as to give off red and green light, respectively.

11. A method as in claim 1, wherein the cast safety light from the safety lighting device is controlled to produce an intermittent operation, for improved attention of boats in the vicinity without blinking at a distress signal level of flashing.

12. A method as in claim 1, wherein the cast safety light from the safety lighting device is controlled to produce an intermittent operation which repeats signals coded by intermittent operation.

13. A method as in claim 12, wherein the intermittent coded signal comprises a Morse code signal.

14. A method as in claim 1, wherein the cast safety light from the safety lighting device produces sufficient light for visibility of the motorboat to other boats in the vicinity without producing forward navigation aid lighting for the motorboat during daylight operations.

15. A method as in claim 14, wherein the cast safety light from the safety lighting device produces a light level of between about 20 to about 100 lumens.

16. A method as in claim 1, wherein the power source comprises one of a battery or generator-created electricity.

17. A method of providing marine safety lighting for a boat of the type having an engine and an associated ignition therefor, comprising:

providing a boat with controllable relatively dim lights adjacent the bow area of the boat;

automatically activating the lights whenever the boat ignition is on; and

continuing to activate the lights while the boat engine is operating.

18. A method as in claim 17, wherein:

the lights comprise respective white lights and colored lights; and

the method further comprises automatically activating only the white lights whenever the boat ignition is on during daylight ambient conditions, and automatically activating only the colored lights whenever the boat ignition is on during not-daylight ambient conditions.

19. A method as in claim 18, wherein:

the white lights comprise a pair of white lights on respective sides of the bow area of the boat; and

the colored lights comprise respective red and green lights on respective port and starboard sides of the bow area of the boat.

20. A method as in claim 17, wherein the light has strength of at least about 20 lumens.

21. A method as in claim 17, wherein the light automatically flashes at less than 50 times per minute.

22. A method as in claim 17, wherein the light automatically flashes per a preselected Morse code signal.

23. A method as in claim 22, wherein the preselected Morse code signal comprises repetition of a two-letter sequence for the letters “

QD”

to indicate that the boat is moving ahead.

24. A marine lighting system for increasing visibility of a motorboat of the type having an engine and an associated ignition, comprising:

a light emitting safety lighting device adapted to be positioned in the bow area of a motorboat to controllably cast safety light in an outward direction from the motorboat;

a power source and a circuit connected with the safety lighting device and the engine of the motorboat; and

a switch in the circuit situated so at automatically energize and illuminate the light emitting safety lighting device with the power source in response to operation of the engine of the motorboat, whereby cast safety light from the safety lighting device increases visibility of the motorboat to other boats in the vicinity of the motorboat whenever the engine thereof is operating, for safety purposes.

25. A system as in claim 24, wherein said safety lighting device comprises a pair of white lights to be positioned on either side of the motorboat bow.

26. A system as in claim 25, wherein:

said safety lighting device further comprises an additional pair of respectively colored lights to be positioned on either side of the motorboat bow;

a light-sensitive sensor for mounting on the motorboat to detect ambient light conditions around the motorboat; and

said switch is operatively associated with said light-sensitive sensor, for controllably energizing only said pair of white lights whenever detected ambient light conditions around the motorboat indicate daylight conditions, and for energizing only said pair of respectively colored lights whenever ambient light conditions around the motorboat indicate other than daylight conditions.

27. A system as in claim 26, wherein said colored lights comprise respective red and green lights to be positioned on respective port and starboard sides of the bow area of the motorboat.

28. A system as in claim 27, wherein said system is combined with a motorboat with said pair of white lights positioned on either side of the motorboat bow, and with said respective red and green lights positioned on respective port and starboard sides of the bow area of the motorboat.

29. A system as in claim 24, wherein the cast safety light has strength of at least about 20 lumens.

30. A system as in claim 24, wherein the switch includes a control chip for automatically flashing the cast safety light at less than 50 times per minute.

31. A system as in claim 30, wherein the control chip is operative for automatically flashing the cast safety light per a preselected Morse code signal.
