Navigation Lights and Precautions at Night

Navigation lights help you and other boaters determine which is the give-way vessel when encountering each other at night. These lights must be displayed from sunset to sunrise and during periods of restricted visibility, such as fog. There are four common navigation lights: sidelights, sternlights, masthead lights, and all-round white lights. At night, make sure your lights are working correctly and carry extra bulbs. If visibility is severely restricted, use your sound signals to alert others in the area.
