Question 133Electricity & Electronics - 1st Asst/Chief

The correct answer is A) stern light "2" burns out. When the stern light circuit fuse blows open, the stern light "2" will go out, indicating the same visual cue as when the stern light itself burns out. This is because the blown fuse interrupts the electrical circuit powering the stern light, causing it to extinguish. The other options are incorrect because they do not directly relate to the visual indication of the stern light going out. A trouble buzzer coil or relay opening would not produce the same visual effect, and a trouble lamp burning out is not the same as the stern light itself going dark.
