🔍 Key Concepts

• Sector lights on lighthouses and beacons • Color changes indicating safe water vs. danger sectors • Difference between a light’s characteristic (flash pattern) and its color sectors

💭 Think About

• When a lighthouse light changes from white to red as you move past it, what does that suggest about your position relative to dangers marked on the chart? • How are danger areas such as shoals, reefs, or obstructions commonly shown using the colored sectors of a lighthouse light? • Which choice describes something that would stay the same regardless of your vessel’s exact position around the lighthouse?

✅ Before You Answer

• Check how sector lights are depicted on a nautical chart and what the red sector usually covers. • Confirm that a light’s identifying characteristic refers to its pattern (e.g., flashing every 5 seconds), not to where its color changes by bearing. • Verify which options describe a fixed property of the light versus a position-dependent warning that changes as you move.
