🔍 Key Concepts

• Light List use for positive identification of aids to navigation • How light characteristics (period, color, flash pattern) are published and used • Limitations of using only color or apparent intensity when identifying lights at night

💭 Think About

• Ask yourself which method gives you an objective, verifiable identification that matches official publications, rather than just what you see. • Consider whether buoy lights are always limited to only certain colors in all situations and areas. • Think about how reliable apparent brightness is when distance, weather, and background lighting can all change how bright a light looks.

✅ Before You Answer

• Verify which choice involves comparing observed information to an official publication. • Check whether any option relies only on visual impressions (brightness, simple color) that can be misleading at sea. • Confirm whether a method would still work in poor visibility or at an unknown distance from the light.
