🔍 Key Concepts

• Light List purpose and what information it normally provides about aids to navigation • Differences between light characteristics: period, rhythm, and color • Which properties of a light are fixed design characteristics versus which can change with conditions

💭 Think About

• Think about what details mariners actually look up in the Light List when trying to confirm an aid to navigation at night. • Ask yourself: when you see a light at sea, which of these characteristics can you time or observe visually, and which may be unreliable at long range? • Consider which of the options is not a standard descriptive field used to uniquely identify a light in official publications.

✅ Before You Answer

• Verify which light characteristics are routinely listed in the Light List (for example: color, period, and type of flashing). • Consider whether intensity is a dependable, observable characteristic for positive identification, especially at different distances and in varying weather. • Check which characteristics are used to define a light’s “characteristic” in chart and publication notations (e.g., Fl R 4s).
