What defines a 'Major Light' in maritime navigation?

A 'Major Light' in maritime navigation is defined as a high-intensity, reliable light emitted from a fixed structure. These lights are crucial for maritime safety as they serve as prominent navigational aids, helping to guide vessels safely through coastal areas, into harbors, and around hazards. The characteristics of a Major Light include not only its brightness but also its consistency and reliability over time, making it a trusted point of reference for mariners.

Fixed structures that emit Major Lights are typically lighthouses or similar installations, ensuring that the light is visible from considerable distances under various weather conditions. Their high intensity allows them to be seen from far away, which is essential for vessels navigating in open waters.

In contrast, other types of lights, such as those from vessels, fog signals, or temporary lights, do not meet the rigorous standards required to be classified as Major Lights. This distinction is important for sailors who rely on various navigational aids, as understanding the differences helps them to interpret signals and maintain safe passage at sea.
