A lighted post cap assembly includes a base member with a generally square shape, a floor, and a plurality of perimeter side walls. The base member is configured to receive an upper end of a post and the floor defines at least four alignment guides and at least four rectangular shaped through holes. Each alignment guide and each rectangular shaped through hole is disposed proximate a respective perimeter side wall. A plurality of light sources are contained within a housing, and each light source is configured to be received by a respective alignment guide at a respective rectangular shaped through hole and oriented downward to illuminate a perimeter of the post. A cover has perimeter side walls and a roof and is secured to the base member such that the plurality of light sources contained between the base member and the cover.

A lens for a trailer light includes a body that transmits light when exposed to light, and a pad operable to mount the lens in front of a light emitting device. The body has a first edge and a second edge located opposite the first edge. The pad is configured to position the body away from the light emitting device such that, when the lens is mounted in front of the light emitting device, a passage is formed between the light emitting device and the body. The passage that is formed has a first opening defined by the first edge of the body, and a second opening defined by the second edge of the body. The first and second openings are configured such that water enters the passage when the lens is mounted to the light emitting device and the lens and light emitting device are submerged in water, and the passage does not hold water when the lens and light emitting device emerge from being submerged in water.

A buoyant illuminated board having a board assembly with a deck, a bottom, first and second lateral sides, and at least one aperture. An electrical system has a power source, and at least one light source within the at least one aperture. A hatch assembly has a lid, and a housing that defines a cavity. The electrical system further comprises a controller, an amplifier, and a battery charger connector that are housed within the hatch assembly along with the power source. The at least one aperture may be elongated to define a channel. The at least one light source is a bulb, a light, a lamp, a light-emitting diode, a light-emitting diode strip, or rope lighting. The board assembly also has an exterior cover that covers the at least one light source within the at least one aperture, and may have a battery charger to recharge the power source.

A submersible marine lighting apparatus is provided that includes voltage up-conversion and that is configured to intensify emitted light by reducing a transmission angle of the light through one or more techniques including increasing the distance between the light emitter and an optical lens.

Enclosures for deep ocean or other high exterior pressure environment including a dome window with an angular measurement of between 164 and 178 degrees, a structure housing, a dome support ring, and a compliance material positioned between the dome support ring and housing are disclosed.

A pivoting rail mounted lighting system for boats which includes three separate portable housings and a light source located in these housings. Each light source being visible from outside the housing such that when the first housing is illuminated, a red colored light source is illuminated for rail mounting to the Port side of the vessel, when the second housing is illuminated, a green colored light source is illuminated for rail mounting to the Starboard side of the vessel, and when the third housing is illuminated, an All Around white light is illuminated for rail mounting to the portions of the vessels railing systems. A quick connect and release pivoting bracket is connected to the housings and is designed to releasably connect to multiple positions along boat railings and allow the light housings to be pivoted into the proper direction to display the correct angle of light.

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.

Enclosures for deep ocean or other high exterior pressure environment including a dome window with an angular measurement of between 164 and 178 degrees, a structure housing, a dome support ring, and a compliance material positioned between the dome support ring and housing are disclosed.

A light assembly and method for installing the same on a surface in a wet or outdoor environment, e.g., on a marine vessel or land recreational or other vehicle, such as marine light assemblies, without need for specialized tools or mounting assemblies. The light assembly comprises a flexible diffusion housing having a first portion and a second portion, with a groove therebetween. A light element is disposed within the interior of the first portion, and light produced by the light element is diffused by the first and second portions prior to emission outwardly from the second portion. After installation, only the second portion of the light assembly is visible on the marine vessel or land recreational surface.

The utility model discloses an inflatable product with a light-emitting positioning structure, including: a main body provided with an inflation chamber inside, and an external bin disposed on the main body, and configured to receive a luminous body; wherein the luminous body received in the external bin can be fixed relative to the external bin when the inflation chamber is in an inflated state; and the external bin and/or the main body can transmit light. The main body of the inflatable product with a light-emitting positioning structure according to the utility model is provided with a self-contained external bin, after the inflatable product is inflated, a light bar located in the external bin can be driven to be attached relative to the external bin, so that the fixing of the light bar is more convenient, and the light bar is not easy to fall off, and the safety is high; at the same time, different light bars can be selected and replaced according to the user's own needs, and the degree of freedom is high; and the light bar is disposed in the external bin capable of transmitting light, which has a good light transmitting effect.
