Each year around the third week of November they light the Pigeon Point Lighthouse and let the 24 main beams remain still for about 5 minutes so photographers can take long exposure pictures of the lighthouse. Afterward the beams begin to rotate so that to a distant ship, they will see one flash every 10 seconds. I have been to this event several times since learning about it a number of years ago. Each year is different and more and more photographers show up.
