A single white light on a boat is usually used as an indication that there’s not much wind.
A “white light seen from behind the boat” is a common occurrence on boats. The lights are used to signal other boats and ships in the area.

What does a single white light on a boat at night imply, for example?

What should you do if a single white light appears immediately front of you?

Similarly, you could wonder what a white light on a boat means.

Masthead Light: All power-driven boats are obliged to have this white light that shines forward and to both sides.
On a boat, where do the lights go?
On a dark, clear night, the necessary lights are red and green sidelights visible from a distance of at least two miles—or one mile if less than 39.4 feet (12 meters) long. If the vessel is less than 39.4 feet long, an all-around white light or both a masthead light and a sternlight are required.
