I am sorry but this is quite mistaken.
Lighted buoys were in common use in Victorian times.
They used gas, often acetylene. One of the cases that determines what is, or is not, a ship is "The Gas Float "Whitton"", which reached the House of Lords in 1897. It turned on whether a lighted buoy in the River Humber might properly be a subject of salvage, and you may see the buoy today here: http://www.geograph.org.uk/photo/755328
