Various implementations described herein are directed to providing lighting in an underwater transducer mounted to a boat. The transducer assembly includes a housing. The housing includes a transducer. The housing includes one or more lighting devices. The housing also includes an element integrated with an outer edge of the housing in a waterproof configuration. The element allows light from the one or more lighting devices to emanate outward from the outer edge of the housing.

A system and method for lighting a surface, for example a deck of a boat, spa, swim spa, pool, watercraft or vehicle, using backlighting such that decorative or other desired patterns of light may be created by forming cuts, outlines, thin sections, or voids in an overlay that is applied to the lighted surface, allowing light to pass through or around portions of the overlay material. In an exemplary use of the system and method of the invention, the surface may be the surface of a boat or spa. The surface may comprise transparent or translucent materials, allowing light from a first side of the decking, or light that is generated within the decking, to pass through the decking and to emanate from a second decking side, where the light may be blocked, partially blocked, or allowed to pass through the overlay material in any desired pattern or shape.

A system for illuminating a class of watersport boards. The system includes a light on the top of the board and a light-transmitting fin on the underside of the board. The board-top light and the light-transmitting fin are fastened together with fasteners that pass through the board. The board-top light contains a battery and energizes the light-transmitting fin through an energy-coupling. Electrically conductive paths and translucent channels are both discussed as energy couplings. An inductive charging connector is provided for charging the battery. Remaining service-time is reported to a user based on battery charge. Additional sensors, such as light sensors, and a microcontroller allow the unit to turn on automatically when ambient light falls below a programmed threshold.

Disclosed is a glide path indicator (2) comprising a light emitter (20) configured to emit a visible light signal that defines a glide path (14) for use by a pilot of an approaching aircraft (10), and a camera (22) configured to capture images of the approaching aircraft (10), the camera (22) being arranged such that at least part of the glide path (14) defined by the light emitter (20) is located within a field of view of the camera (22). The glide path indicator (2) may be mounted to a vehicle (4), for example, an aircraft carrier. The glide path indicator (2) may further comprise a stabilisation module (26) configured to stabilise the light emitter (20) and the camera (22) so as to reduce or eliminate the effects of the vehicle's motion on the glide path (14) and the field of view of the camera (22).

The present invention discloses a sector light, said sector light having at least one tier including a light source assembly comprising opaque dividing elements, two or more light sources, and two or more optical lenses; wherein the light source assembly is divided into circumferential sections, each circumferential section being separated by the opaque dividing elements, and each circumferential section containing a light source and an optical lens arranged such that the optical lens collects and outwardly projects the light emitted by the light source.

A distress signal system for a sea vessel comprises several navigation lights (11, 12, 13, 14, 15), which are connected in an electrical circuit and arranged to emit a steady light in different directions in a normal operating state. The distress signal system comprises a control means (28, 30) connected to the electrical circuit which in a distress signal state is arranged to vary the current to the navigation lights (11, 12, 13, 14, 15) in order to vary the light emission therefrom in accordance with a distress signal, such as SOS. A manually actuatable actuator (24) is connected to the control means (28, 30) to activate or deactivate the distress signal state. A light activating means (26) is arranged to provide a varied power supply to the navigation lights (11, 12, 13, 14, 15) in connection with activating the distress state, regardless of whether these are in operating state or not. Such a distress signal system can be provided by connecting a separate distress signal unit comprising a control means to the navigation lights of a sea vessel.

The present invention is directed to an electronic visual distress signal device or emergency beacon. Specifically, the visual distress signal device has a housing containing a power source and an electronic assembly that is operably coupled to the power source The electronic assembly includes a light source so that when the power source and the electronic assembly form a closed circuit, the light source is activated. The light source may be configured to emit an SOS signal. Furthermore, the device may include a lens member that is configured to refract light emitted by the light source in at least two separate patterns including a 360 degree horizontal pattern and a vertical pattern. The visual distress device may include a float member formed of compressible foam to permit the device to float when placed in water.

The invention provides a visibility aid for watercraft in the form a stream of water illuminated from within so that the stream of water is readily visible even in unfavorable conditions. A stream of water such as the telltale from the cooling system of an outboard motor is illuminated from within by light that exhibits total internal reflection. This makes the telltale easy to see, even at night, allowing a boat operator to know that the cooling system is functioning properly.

The present invention is directed to a visual distress signal device that includes a housing having an internal cavity with a first electrical contact and a power source positioned therein in an electrically coupled manner. An electronic assembly is at least partially positioned within the internal cavity of the housing. Such an electronic assembly may include a second electrical contact that is electrically coupled to the power source, a third electrical contact, and a light source. The device may also include a lens member detachably coupled to the housing to close an open top end of the housing in a watertight manner. A float member may be detachably coupled to the housing to provide buoyancy to the device. The electronic assembly may be movable within the internal cavity to electronically couple and decouple the third electrical contact and the first electrical contact to selectively power the light source.
