Navigational Light Set

A navigational light set, also known as navigation lights or running lights, is a system of lights used on various types of vessels to indicate their position, direction of travel, and status to other vessels and observers. These lights are essential for safe navigation, especially during periods of reduced visibility or at night.

The navigational light set typically consists of three lights: a red light on the port (left) side, a green light on the starboard (right) side, and a white light at the stern (rear) of the vessel. These lights are positioned and angled in specific ways to provide clear and unambiguous signals to other vessels.

The red light on the port side indicates that the vessel is approaching from the observer's left side. The green light on the starboard side indicates that the vessel is approaching from the observer's right side. The white light at the stern indicates the presence of a vessel and its direction of travel.

In addition to these lights, larger vessels may also have additional lights, such as masthead lights, sidelights, and stern lights, to further enhance their visibility and indicate their size and maneuverability.

Navigational light sets are regulated by international maritime organizations, such as the International Maritime Organization (IMO), and are standardized to ensure consistency and safety across different vessels and waterways.

It is important for all vessel operators to understand and comply with the regulations regarding navigational lights to prevent collisions and ensure the safety of everyone on the water.
