When boating at night, a single white light tells you that it is either a light house or an anchored boat.
You are looking at the Starboard (right) side of the boat. If you can't see the white stern light then that boat is pointed toward you.
If you are boating at night, and you see a single white light on another boat this light tells you that you are overtaking another vessel or it is anchored. It is mandatory for all engine powered boats and shines forward. If there is no light it indicates a sailboat under sail.

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.
