During a nighttime operation on a powerboat, what lights must be displayed?

During nighttime operation on a powerboat, displaying a white stern light along with red and green sidelights is essential for ensuring visibility and safety on the water. The white stern light illuminates the rear of the vessel, making it visible to approaching boats from behind. The red and green sidelights indicate the direction the boat is facing—red on the port side (left) and green on the starboard side (right)—which helps other vessels determine the boat's orientation and prevent collisions.

Properly displaying these lights is critical not only for the operator's awareness but also for the safety of other boaters, as they provide necessary information regarding the boat's position and movement. Other combinations of lights, such as those listed in the incorrect options, do not meet the standards set by navigation rules for nighttime operation, as they might not provide clear guidance about the vessel's direction or are not recognized for use on the water at night.
