A signal mirror enabled this rescue - but don't count on getting this lucky ...

The fisherman was rescued when the signal mirror suspended from his neck reflected light to his rescuers ... at night! (1:30 AM)

Rescuer quote: “We were under night vision goggles, looking around and we saw a flash of light from his signal mirror that he happened to have around his neck,”

The moon was 88% full that night, so the reflection off the mirror may have been the moon.

I've used a signal mirror to deliberately flash moonlight but this is the first account I recall where an accidental moon reflection was credited.

Edit Reason: Another mention of mirror
A signal mirror should backup a radio distress signal, like a 406 MHz PLB (ACR PLB) (Ocean Signal PLB)
