🔍 Key Concepts

• Use of the U.S. Coast Guard Light List to determine characteristics of aids to navigation • Typical operating schedule of major navigation lights on prominent points or capes • Meaning of a light’s height above mean low water compared to when it is illuminated

💭 Think About

• Which of these options describes a permanent characteristic of a major aid to navigation, rather than a seasonal or conditional one? • Think about the purpose of a lighthouse on a busy approach like Orient Point — when would mariners potentially need it most? • Which statements sound unusual compared with what you know about how most major coastal lights operate?

✅ Before You Answer

• Check how the Light List presents light characteristics: does it usually list operating hours, height, or seasons? • Consider whether a major point light would reasonably be limited to daytime only or summer months only in a high‑traffic area. • Verify which option reflects a standard, published characteristic (such as a fixed height or continuous operation).
