When are navigation lights required to be displayed?

Navigation lights are required to be displayed from sunset to sunrise. This regulation is in place to ensure the safety of all vessels on the water during hours of low visibility, such as nighttime. By using navigation lights, boat operators are able to communicate their position and movement to other vessels as well as to ensure they can see any potential hazards in the water. This is crucial for preventing collisions and enhancing overall maritime safety.

During daylight hours, it is generally expected that visibility allows for safe navigation without the need for artificial lights. In foggy conditions, however, the use of navigation lights may still be necessary, but those conditions specifically warrant additional sound signals rather than just relying on the lights alone. This nuance further emphasizes the importance of visibility and safety regulations that dictate when navigational aids should be employed on the water.
