As shown in the illustration, what event would give the same indication that would occur when a stern light circuit fuse blows open? Illustration EL-0058

Correct Answer: Option A — stern light "2" burns out

Navigation light monitoring panels utilize current-sensing relays in series with running lights. If stern light #2 burns out, current ceases through the sensing coil, causing identical alarm and indicator light transitions as a blown circuit fuse within the monitored circuit.
