If a vessel is not underway at night, which light may be shown?

Explanation:
When a vessel is not underway at night, it should show a white all-round anchor light. This signals to other mariners that the vessel is stationary and anchored, helping to prevent collisions by making its position visible from anywhere around the vessel. The other lights serve different purposes: sidelights indicate the vessel’s presence from the sides when moving, a white stern light is part of the lighting used when the vessel is underway, and a red port light also signals navigation status while the vessel is moving.
