Lighthouse lamps through the years

Lighthouses used oil-fuelled lamps throughout the first half of the 20th century. The lighthouse keeper would light a wick dipped in a reservoir of oil, creating an intense flame and a strong light. When a ship was expected, the lighthouse keepers would be notified so they could light the lamps. When the St. Lawrence Seaway was opened year-round, the lighthouses were switched to battery-powered electric lamps. Today, the range lights are powered by solar panels.
