The red light is displayed on the port side, and the green light on the starboard side, while the all-round white light indicates the vessel's presence and helps prevent collisions. This lighting configuration is essential for visibility and safety on the water.
If you encounter a vessel displaying only a visible white light, it is most likely a power-driven vessel that is underway.

Be cautious and keep a lookout for any other lights displayed by the vessel to determine their course and intentions.
