When seen together at night, a red and green light typically indicates the presence of a vessel or boat. The red light is on the port (left) side, while the green light is on the starboard (right) side, following maritime navigation rules. This combination often suggests that the vessel is approaching head-on or crossing paths, helping to determine its direction and avoid collisions. In aviation, similar colored lights can indicate the position of an aircraft.

The masthead light is typically white in color. It is displayed at the top of a vessel to indicate the presence of another vessel at night.

When seen together at night, a red and green light typically indicates the presence of a vessel or boat. The red light is on the port (left) side, while the green light is on the starboard (right) side, following maritime navigation rules. This combination often suggests that the vessel is approaching head-on or crossing paths, helping to determine its direction and avoid collisions. In aviation, similar colored lights can indicate the position of an aircraft.
In darkness or reduced visibility, the white light indicates a vessel's stern, while red and green lights indicate the port (left) and starboard (right) sides, respectively. A vessel displaying a red light is facing another vessel, while a green light indicates it is on the starboard side. This color coding helps mariners determine the direction and type of vessel they are encountering, ensuring safe navigation.

Red indicates the port (left) side of the boat, green indicates the starboard (right) side.
In darkness or reduced visibility, visible red and green lights on a vessel indicate its orientation and direction of travel. A steady red light on the port (left) side and a steady green light on the starboard (right) side signify that the vessel is underway and facing the observer. If you see both red and green lights, it means you are approaching the bow of the vessel. If only one light is visible, it indicates the vessel's side, helping you assess its direction and take appropriate navigational actions.
A commercial vessel towing at night displays a white towing light above the stern of the towing vessel and a second white light at the stern of the tow. Additionally, the vessel should show a green light on the starboard side and a red light on the port side, as well as an all-round white light at the stern of the vessel being towed. These lights help indicate the vessel's activity and ensure safe navigation for other vessels.
The color light that must show on the starboard side of a boat is green. This green light is part of the navigation lights used to indicate the direction the vessel is facing and helps prevent collisions at night or in low visibility conditions. The starboard (right) side green light is typically visible from 112.5 degrees, along with other navigation lights on the vessel.
The masthead light is typically white in color. It is displayed at the top of a vessel to indicate the presence of another vessel at night.
