Where is the stern light visible from?

The stern light is specifically designed to be visible from behind or nearly behind the vessel, ensuring that other vessels approaching from that direction can see it. This is essential for safety on the water, as it helps to prevent collisions during nighttime or reduced visibility conditions.

Stern lights are part of the navigation lighting requirements for vessels and are typically mounted at the stern (or rear) of the boat. When properly illuminated, they provide a clear indication of the vessel's position and direction to other boaters who may be approaching from the rear.

Other options do not accurately represent the purpose of the stern light. It is not intended for visibility from the sides or front, nor is it meant to be seen from all directions. Instead, its primary function is to signal that there is a vessel present and indicate where it is located in the water when viewed from behind.
