The Troubridge Island Lighthouse was completed in 1855, and was the second lighthouse to be built in South Australia. It is constructed of cylindrical cast iron segments shipped out from Britain and bolted together on site. In 1882, the light was upgraded to a holophotal reflector apparatus and lantern. Between the years 1925 and 1931, the operation was electrified, powered by a petrol generator. In 1956 the light was again upgraded to a 1000 watt tungsten halogen lamp. This increased the range from the original 10 miles to 25 miles. Also the 24 m height light tower was repainted from the original colours to bright red with a white horizontal band as a day mark. In the late 1970s, it was decided to build a new lighthouse on Troubridge Hill. The new light was completed in 1980 and in 1981 the Troubridge Island is the passage of water between Kangaroo Island and the Yorke Peninsula. The shoal hugs the Yorke Peninsula and officially has been the cause of 33 wrecks and groundings. In 1850, 7 vessels ran aground in 8 months. Troubridge Island light was downgraded in power, automated and demanned. In 1982, the island and lighthouse was sold to the South Australian Government who wished to create a bird sanctuary. The light was extinguished in March 2002 and replaced by a beacon on Marion Reef. It was ironical that this was the the very same month that Australia Post honoured the light with a postage stamp.
