Which signaling device can substitute for running lights on very small craft when running lights are unavailable?

• A. Lantern
• B. Flashlight
• C. Candle
• D. Beacon

Answer: (B)

When trying to show your vessel’s presence at night, you need a light that other boats can see to indicate you’re underway. A portable light used properly can stand in for running lights on very small craft when the standard lights aren’t available. A flashlight fits this need best because it’s compact, easy to carry, and can be directed or held aloft to make your vessel visible to others, helping them gauge your position and approach. A lantern can be used, but it’s less reliable in wind and movement and may not meet the necessary visibility range. A candle is easily extinguished and unreliable in open water. A beacon is a fixed navigational aid and isn’t something a small, moving boat carries to substitute for its own lights.
