Spotting a red and a green light on a boat at night is an indication that the boat has its bow pointed in your direction. If the boat is under way, it's coming at you.
The red light is on the port or left side, the green on the starboard or right. These lights cannot be seen from dead astern, and only one color can be seen from beside (abeam) of the vessel.
