The function of a light buoy is indicating the location of underwater hazards, such as rocks or shallow areas.

A buoy navigation light is an essential component of maritime safety. These lights are strategically placed on buoys to help guide ships and boats through waterways, especially at night or in low visibility conditions. They serve as beacons, indicating the presence of navigational hazards, such as rocks, shoals, or channels.
Buoy navigation lights are typically powered by solar panels or batteries, ensuring they remain operational even in remote locations where access to electricity may be limited. They are designed to withstand harsh weather conditions, such as strong winds, heavy rain, and rough seas. Regular maintenance and inspections are conducted to ensure their proper functioning.
