Which flashing pattern is labeled Quick Flashing?

Which flashing pattern is labeled Quick Flashing?

• A. Single flashing
• B. 60 flashes per minute
• C. Safe speed
• D. Quick Flashing

Answer: (D)

Understanding how flashing patterns are described on navigational lights helps you identify aids at night. If the chart or light-list uses the descriptor Quick Flashing, that exact phrase is the label for that light pattern. So choosing the option that literally says Quick Flashing is correct because it matches the terminology used to describe that pattern. The other options describe different things: a single flashing is just one flash, not a rapid sequence; a numeric rate like 60 flashes per minute refers to how often the light would flash but isn’t the named category used on charts; and Safe speed is unrelated to light characteristics.
