Why are lighthouses still kept?
For many years, lighthouses still had keepers, partly because lighthouse keepers could serve as a rescue service if necessary.

In Canada, this trend has been stopped and there are still 50 staffed light stations, with 27 on the west coast alone.
How does a lighthouse work?
In early lighthouses, the light source was a kerosene lamp or, earlier, an animal or vegetable oil Argand lamp, and the lenses rotated by a weight driven clockwork assembly wound by lighthouse keepers, sometimes as often as every two hours.

These also supplied electricity for the lighthouse keepers.

What is the luminous range of a light?
The luminous range of a light is the limiting range at which the light is visible under prevailing atmospheric conditions and disregarding limitations caused by its height and the Earth’s curvature. A very powerful light, low in position, can thus have a clear-weather luminous range greater than that when first seen by the mariner on the horizon. Powerful lights can usually be seen over the horizon because the light is scattered upward by particles of water vapour in the atmosphere; this phenomenon is known as the loom of the light.
