In some embodiments, a lighting assembly including at least one light-emitting device positioned within a housing is disclosed, wherein the housing is designed to allow an ambient environment to pass into the housing and transfer heat from the at least one light-emitting device. The light-emitting area of the light-emitting device may be sealed from the ambient environment. In some embodiments, the housing may include at least one recess, port, or other opening configured to allow a liquid or gas to promote heat transfer from the light-emitting device. In some embodiments, a vehicle, a marine system, or other systems may include at least one lighting assembly as contemplated herein.

A garboard drain plug system comprising an ergonomic grip which may aid in tightening and loosening the drain plug by hand without special tools. The garboard drain plug system may comprise a light ring which may surround a garboard, and thereby illuminate an area adjacent to, or surrounding, the garboard. Together, the ergonomic drain plug, garboard, and lighted garboard ring may act alone or in cooperation to provide a method of controlling communication of a fluid through a drain of a hull or transom of a boat or vessel.

An advisory system of a vessel that monitors variables of a vessel system inclusive of systems and subsystems that are used to operate the vessel. The advisory system may use machine-learning to learn from an operator (i) whether or not two variables are related to one another, and (ii) likelihood that a variable will reach a threshold, and, optionally, time until reaching the threshold. The system may receive operator feedback (i) to indicate whether the two variables are related to one another, and (ii) whether a behavior of the variable is normal or not normal. Thereafter, if a determination that the same two variables are related to one another and behaving in a similar manner, provide notification to the operator of the behavior. In response to determining that the variable is behaving (e.g., trending) in a similar manner that is not normal, providing a notification to the operator.

Systems and methods for monitoring, detecting, measuring, altering, optimizing, and/or modifying electrical power delivered to a power consuming device. The power consuming device can be a light, speakers, fans, motors, any household electronic appliance, or other power consuming device. Also disclosed are light assemblies including a first plurality of strings of red LED lights, a second plurality of strings of green LED lights, and a third plurality of strings of blue LED lights (e.g., SMD LEDs). The light assembly also includes a driver configured to intermittently supply power from a power source to the red LED lights, green LED lights, and blue LED lights. The light assembly also includes a housing to house the light assembly, the driver, the power source, and a controller.

A pole light and base system that includes a pole light base configured to be secured to a gunwale of a watercraft. In practice, the pole light base might include a pole light tube and a female Universal Serial Bus connector. The pole light tube may have electrical contacts configured to engage respective electrical contacting portions of an all around light pole if an all around light pole is inserted into the pole light tube. In some cases, the system might include the all around light pole and light. The electrical contacts of the tube might include a positive contact electrically coupled to a first wire and a negative contact electrically coupled to a second wire. The first and second wire may be designed to connect directly to a 12 Volt watercraft battery. They may also connect to a boat fuse box that is connected to a battery. Similarly, the female USB connector can be electrically connected to a printed circuit board that includes transforming components capable of transforming 12 Volt power from a watercraft battery into a lower voltage, such as 5 volt, that is made available via the female USB-A connector.
