The red and green lights are sidelights that are positioned on the port side (red) (left as facing the bow) and starboard (green) (right as facing the bow) side of the boat. Various white lights are required depending on the size of the boat, but generally, a white masthead light and stern light are required. See the US Coast Guard site in the link below for more specific information.
If you see red and green (with the red on the right and the green on the left), it's a vessel heading directly towards you (although its course may be different). The white (single) light would indicate that it is a powered vessel as opposed to a sailing vessel.
If you observe just the red light on a ship, they have the right-of-way and you are to maneuver to stay clear. In this case, both vessels should take precautions. In any case, the default maneuver is to turn starboard (to the right).
Advisory:
Please read the discussion to this question.
When you see a red, a green, and a white light, you are approaching another power-driven vessel head-on and both vessels must give way.

What does it mean when you are operating a powerboat at night and you see red green and white lights on another boat?
When you see red, green, and white lights on another boat at night, it indicates the boat's orientation and direction of travel. The red light (port side) and green light (starboard side) show the sides of the boat, while the white light typically indicates the stern (rear). If you see the red light on the left and the green light on the right, that boat is facing you; if you see their stern white light, they are moving away. This information helps you determine how to navigate safely and avoid collisions.

The green and white lights on another boat indicate that it is a power-driven vessel underway. The green light is typically shown on the starboard (right) side, while the white light is the stern light. This configuration suggests that the other boat is approaching from your right side, and you should be cautious and ready to give way or adjust your course as necessary to avoid a collision.
