A single white light that is visible from all directions indicates a moored vessel. The purpose of this light is to alert other boaters of the vessel's presence, helping to prevent collisions, particularly during the nighttime or in low-visibility conditions. This type of light serves as a signal for other vessels that may be navigating nearby, allowing them to take appropriate precautions to avoid entering the area where the moored vessel is located.

In marine navigation, understanding the significance of various light configurations is crucial for safety. A moored vessel is stationary and requires a specific signaling method to ensure it is noticed by passing watercraft. This is particularly important in busy waterways where many different types of vessels are operating. Other types of lights, such as those indicating a sailing vessel or a navigational hazard, have different color codes or configurations to communicate their specific situations.
