Here are some details about this type of light: Design: The all-round deck mount light is typically designed with a pole-style configuration. It consists of a light fixture mounted on top of a pole, which is then attached to a base for installation on the deck or other suitable location on the boat. 360-Degree Visibility: The purpose of an all-round deck mount light is to provide a full 360-degree illumination, making the boat visible from all angles. This type of light is usually used as an anchor light or as a general navigation light when the vessel is under power or not underway. Construction and Materials: The light fixture is typically constructed with a durable and corrosion-resistant material, such as stainless steel or a marine-grade plastic. The base and mounting hardware are designed to securely attach the light to the deck or other mounting surface. Power Source: The all-round deck mount light is typically powered by the boat's electrical system. It may require wiring and connection to the appropriate power source, such as the boat's battery or a switch panel. Compliance: It's important to ensure that the all-round deck mount light meets the relevant navigation light regulations and requirements for your specific boating jurisdiction. These regulations may specify the light's visibility range, height above the waterline, color, and other factors.
