Navigation lights must be displayed from sunset to sunrise to ensure that vessels are visible to one another during times of limited visibility. This requirement is crucial for maintaining safety on the water, as it helps prevent collisions when it is dark. Boaters are required to use these lights when operating their vessels during night hours to enhance visibility and awareness, contributing to the overall safety of all waterway users.

During the hours of darkness, navigation lights, including sidelights and a stern light, serve a vital function in signaling a vessel's presence and direction to other boats. The use of these lights is governed by regulations that emphasize the importance of visibility for both the operator of the vessel and other nearby vessels. Thus, understanding this requirement is fundamental for safe boating practices.
