What is the minimum continuous operation time for a floating electric marker light?

• A. A minimum of 24 hours of continuous operation
• B. A minimum of 12 hours of continuous operation
• C. A minimum of 36 hours of continuous operation
• D. A minimum of 48 hours of continuous operation

Answer: (C)

The test is about how long a floating electric marker light must run continuously on a single charge to ensure it stays visible during typical operations. The minimum required duration is 36 hours, which covers roughly a day and a half of operation. This ensures the light remains lit through overnight watches or delays in maintenance, providing reliable visibility to other vessels. Shorter durations (12 or 24 hours) could fail during longer operations, while a longer duration (48 hours) goes beyond what’s needed as the minimum standard.
