A sternlight is a white light on the back end of a boat or ship. The configuration depends on the size of the boat. Some small boats have an all around white light. Bigger boats have a light that shows only over an arc of 112 degrees facing aft.

A boat's sternlight is typically white. It is positioned at the stern (rear) of the vessel and is used to indicate the boat's presence to other vessels from behind. The white light must be visible from a specific distance, ensuring safety during nighttime navigation.
All vessels that are moored or anchored outside a designated mooring area between sunset and sunrise must display a white light visible all around the horizon. This light serves to indicate the vessel's presence to other mariners. Additionally, larger vessels may also be required to show sidelights and a sternlight, but the white anchor light is essential for all.
A collective noun for ocean going vessels is a fleet of vessels. A collective noun for drinking vessels is a set of vessels. A collective noun for liquid carrying (in plants and animals) vessels is a system of vessels.
Vessels
A power-driven vessel of less than 12 meters in length may show an all-round white light in lieu of the masthead light and sternlight. This all-round white light must be visible from all directions and is typically mounted at a height that ensures visibility. Additionally, the vessel may also display sidelights if it is engaged in activities requiring them.
It is white and shows an 135 degree arc of visibility, or 67.5 degrees right or left of stern. Please refer to rule 21 of the Navigational Rules of the Road. A link is provided below.
twisted vessels
A vessel displaying sidelights, a sternlight, and two all-round lights in a vertical line is typically a power-driven vessel that is 50 meters or more in length. The two all-round lights indicate that it is engaged in fishing or another specific activity, such as towing or dredging. This configuration helps other vessels identify its activities and navigate safely around it.
