When are navigational lights required to be used?

Navigational lights are a crucial safety feature for boats, as they help ensure visibility and prevent collisions, particularly in low-light conditions. The requirement to use these lights from sunset to sunrise and during periods of reduced visibility is grounded in the need for all vessels to be clearly seen by others. This includes times when fog, rain, or other environmental factors may hinder visibility during the day as well.

By using navigational lights during these specified times, boaters help create a safer environment for themselves and others on the water. Other scenarios, such as merely operating during the day or only in bad weather, do not adequately cover the full spectrum of conditions where visibility may be a concern. Moreover, while boats at anchor do require specific lighting, the more comprehensive rule focuses on the broader context of lighting needs during low visibility situations.
