When are navigation lights required to be displayed?

Answer

From sunset to sunrise and during periods of restricted visibility

Navigation lights must be shown from sunset to sunrise and whenever visibility is restricted, such as in fog. They let other boaters see you and judge your heading and type of vessel.
