A power-driven vessel of less than 12 meters in length may show an all-round white light in lieu of the masthead light and sternlight. This all-round white light must be visible from all directions and is typically mounted at a height that ensures visibility. Additionally, the vessel may also display sidelights if it is engaged in activities requiring them.
A power-driven vessel less than 12 meters in length may carry an all-round white light instead of the standard masthead light and sternlight. This all-round white light must be visible from all directions and should be positioned at or near the highest point of the vessel to ensure visibility. Additionally, the vessel should display side lights when operating between sunset and sunrise.
Generally they are masthead light, port and starboard steaming light and stern light. Others may be displayed depending on the length of the vessel and what duties it is carrying out.
Lighting requirements vary depending on whether you're talking about a sailboat or powerboat, International Rules or Inland Rules, the length of the vessel, and whether or not the vessel is at anchor. However, if at night you see a single white light only (no red or green lights), you're most likely looking at a boat at anchor.
The red (port) and green (starboard) are running lights and can tell you which direction the boat is heading in low visibility conditions. Remember the phrase, "red right returning," which means if the red light is on the right, the boat is returning, or headed towards you. The white light can be a masthead light or a sternlight, and its requirements vary depending on boat length and whether you're operating under international or inland rules.

You give no options but the standard lights depend on things like length overall. A minimum would be port and starboard running lights, masthead light and stern light
what is required on power driven vessels over 9m in lenght
Fishing skiffs (flat-bottomed) are often fifteen feet long or less, and they are power-driven.
Port (red) and Starboard (green) running lights and a white light which will be mounted on either the stern or the masthead.
