The number of Light List volumes is which of the following?

• A. Five
• B. Six
• C. Eight
• D. Seven

Answer: (D)

The idea here is that the Light List is a multi-volume reference, not a single book. It’s published as a set that organizes all navigational lights and aids by region, so mariners can quickly find the information relevant to where they are or where they’re going. In the standard current edition, that set totals seven volumes, covering the many coastal and inland areas you’ll navigate. Each entry within a volume provides the light’s name or position, characteristic (color, flash pattern), range, height, coordinates, and any important remarks, all designed to help you identify and avoid hazards at sea. So seven volumes is simply the established total of the comprehensive Light List; the other numbers would reflect different editions or configurations, not the present standard.
