|Before automation at the Point of Ayre lighthouse it used to be a
leisurely Red and White beam every minute,this used to pass across
one of the local farmers barns where he kept his cows overnight-No
When the light was automated the lamp was changed from 250 watt to
400 watt and character changed to four quick flashes every 20
seconds,after a few nights the farmer was complaining that his cows
were fretful and restless and the only thing he could think of,was the
light beams,so we extended the blank panes (Without compromising
safety) and the cows settled down again.|
