What does an all-round white light serve as when sidelights are extinguished?

1. A distress signal

2. An anchor light

3. A signal for mechanical failure

4. A signal indicating the vessel is under engine power

The correct answer is: An anchor light

When sidelights are extinguished, an all-round white light serves as an anchor light. This light is typically displayed at night when a vessel is anchored to indicate its position to other vessels. The other options are incorrect because - A: A distress signal is typically a red flare or SOS signal, not a white light. - C: A signal for mechanical failure would usually be a red or yellow light, not a white light. - D: A signal indicating the vessel is under engine power would be a green and white light, not an all-round white light.
