 A disastrous fire started on the seventh floor on the night of 16 March 1954 and spread downwards . The keepers had no time to raise the alarm and were driven out of the lighthouse onto the rocks but rescued the next day when the relief vessel arrived as part of its regular schedule . The heat of the fire caused damage to both the interior and the structure and a lightship and series of temporary lights were installed during reconstruction . Three new generators were placed in the lighthouse to provide an electric light source , the lantern being re @-@ lit on 6 August 1959 .
