From sunset to sunrise, when are navigation lights required to be shown?

Explanation:
Navigation lights are required whenever it is dark to make your vessel visible and to convey its presence, heading, and status to others. The time window from sunset to sunrise is the defined period for this requirement, covering the night hours when visibility is low. In daylight, navigation lights aren’t normally needed unless visibility is restricted; and fog is a separate condition that would require lights as well, but it does not override the standard night rule. So the period you must show lights is from sunset to sunrise.
