A tiny flicker of flame from the cigarette lighter turned out to be a life-saver for a 25-year-old mountain climber, who got stuck on a frozen mountain ledge.
The tiny flame was spotted by a helicopter crew using night-vision goggles to peer through a storm eight miles away from the rescue spot.
AdvertisementAs he desperately signalled at regular intervals for help, they followed the faint glimmer to rescue him at last.
"He was flicking his lighter so that he might be spotted - and luckily the flame was just enough for us to pick up through our night goggles," the Mirror quoted Pilot Flt Lt David Moran as saying.
The incident came into light after the climber and three others, including two women, were reported missing after getting into difficulties in Snowdonia, North Wales.
They were stranded near accident blackspot Clogwyn Coch - 2,000ft up Snowdon - after the climber lost his footing and fell 370ft.
