🔍 Key Concepts

• INLAND Rule 34(b) – Maneuvering and warning signals • Requirements for the supplemental maneuvering light (used with whistle signals) • Differences between color, arc of visibility, and synchronization requirements

💭 Think About

• Think about what kind of light best matches the idea of copying the whistle signal visually — where should it be seen from, and how should it behave? • Ask yourself: is the maneuvering light allowed to be any color used in navigation lights, or is it restricted to a specific color? • Consider whether the maneuvering light is required to flash in time with the whistle, or if it can operate independently.

✅ Before You Answer

• Check in INLAND Rule 34(b) what it says about the color of the maneuvering light. • Confirm whether the rule specifies the light must be all-round (visible from 360°) or if a limited sector is allowed. • Verify if the rule requires the light to be synchronized with the whistle signal (same pattern and timing).
