🔍 Key Concepts

• Consulting the U.S. Coast Guard Light List or the chart for light characteristics • Understanding how a light’s color and period (in seconds) are described in the characteristic • Knowing that the characteristic describes one complete cycle of the light pattern

💭 Think About

• Look at how light characteristics are normally written on charts (e.g., Fl R 4s, Fl W 6s). Which of the answer choices matches the actual published characteristic for Brandford Reef Light? • Think about the typical color used for many major reef lights in that area and the usual flashing period—does it more often match 3s, 4s, or 6s? • Consider that both color and period must match exactly; which option fits the known published data for Brandford Reef Light?

✅ Before You Answer

• Verify the entry for Brandford Reef Light in the current Light List for its color and period • Confirm that you understand that "Flashing" means the light is on for a short time and off longer within each complete cycle • Double‑check that you match both the color (red/white/yellow) and the correct time interval in seconds before choosing an option
