🔍 Key Concepts

• IALA buoyage light characteristics (how different types of lights are defined) • Difference between rhythmic light types: flashing, occulting, isophase, alternating • What the term alternating specifically refers to in light descriptions on charts and Light Lists

💭 Think About

• Focus on what changes in an alternating light: is it the length of time the light is on, the direction, the intensity, or the color? • Think about how an alternating light would be written in a Light List or on a chart (for example, how would they show two different colors vs. one color with different on/off times?). • Which answer clearly describes a distinguishing feature that mariners would need to recognize at night to identify the aid to navigation?

✅ Before You Answer

• Check which option refers to a change in color versus a change in timing or use. • Verify that an alternating light is a formally defined light characteristic, not just an operational choice or a backup/replacement. • Eliminate any option that describes something that could also apply to other light types (like varying on/off times), and look for what is unique to alternating lights.
