A boat stern light is a crucial navigation light that helps prevent collisions on the water, especially at night. It signals the boat’s direction to other vessels. But what color is it? The answer is white.
Understanding Boat Stern Lights
A stern light emits a white light that covers a 135-degree arc, shining from dead astern (directly behind the boat) to 67.5 degrees on either side. This wide angle ensures visibility from various positions behind the boat.
Why White?
The color white was chosen for stern lights for its excellent visibility in low-light conditions. It provides a clear contrast against the darkness, making it easier for other boaters to identify the vessel’s presence and direction of travel.
Other Navigation Lights
While the stern light is white, it’s crucial to remember that boats use a system of colored navigation lights:
- Port (Left) Sidelight: Red, visible from the port (left) side of the boat.
- Starboard (Right) Sidelight: Green, visible from the starboard (right) side of the boat.
- Masthead Light: White, visible from the front of the boat.
These colored lights, along with the white stern light, allow boaters to determine the direction and approximate course of other vessels in the vicinity.
Importance of Proper Lighting
Properly functioning and visible navigation lights are essential for maritime safety. They enable boats to:
- Avoid collisions, especially in low visibility conditions.
- Signal their position and direction to other vessels.
- Navigate safely through channels and waterways.
Legal Requirements
Navigation light regulations are standardized internationally by the International Regulations for Preventing Collisions at Sea (COLREGs) and enforced by local authorities. Boat owners are legally obligated to have functioning navigation lights that meet the specified requirements for visibility, color, and arc of illumination.

Conclusion
Understanding the color and purpose of boat navigation lights is vital for anyone operating a vessel. The white stern light plays a crucial role in preventing collisions by clearly signaling a boat’s direction. Remember to adhere to all regulations and prioritize safety when navigating waterways.
