At minimum what should a rowboat be able to display at night to prevent a collision?

At a minimum, a rowboat should display a white light visible from all directions at night to prevent collisions. This light can be either a flashlight or a lantern that is mounted to ensure visibility. Additionally, if the rowboat is in a specific area where regulations apply, it may also need to show red and green sidelights. Following the appropriate maritime regulations for nighttime visibility is crucial for safety.
