Which of the following is a consideration when installing navigation lights on a boat?

When installing navigation lights on a boat, the priority is to ensure that they are installed in a manner that avoids obstruction. This means placing the lights in locations where they can be seen clearly from other vessels and where they do not get blocked by any part of the boat, such as superstructures, sails, or other equipment. Proper visibility is crucial for safety, as navigation lights are essential for communicating a vessel’s position, heading, and operational status to other boats, especially during low visibility conditions such as fog or at night.

While other factors may be relevant in specific contexts—such as brightness for daytime use or the necessity for battery power—the most critical aspect during installation is their effective visibility. This ensures compliance with maritime regulations and promotes safety on the water.
