Exterior LED Lights


Definition of Exterior LED Lights

docked boats with exterior LED lights

Exterior LED lights are light fixtures mounted on the outside area of any marine vessel that use light-emitting diode (LED) technology.

They are designed to provide crucial illumination to the exterior of the vessel and enhance visibility during low-light conditions, such as nighttime navigation.

Not only do these lights improve safety on board by illuminating surrounding waters, but they also add aesthetic appeal to your vessel.

Compared to traditional incandescent bulbs, which consume large amounts of energy, exterior LED lights are more efficient, long-lasting, and have high-performance capabilities.

LEDs use less power while delivering a bright light output that can last up to 50 times longer than incandescent lights.

LED technology additionally has innovative designs incorporating smart controls such as dimming features and color-changing modes. This allows you to customize your exterior lighting according to different situations, such as fishing versus docking in harbor areas.

Depending on their intended function and location on the vessel, exterior LED lights are categorized into several types, as shown in the table below.
