It holds the world record for the longest running light bulb.
How many firemen does it take to change a light bulb? Well, at the fire station in Livermore, California in the US the answer has been none for over a century.
The humble 60 watt, handblown lightbulb made by Shelby Electric Company in 1901 is still hanging in the fire department and still burning as bright as ever.
It has lived longer than all its fellow bulbs and is just shy of the longest lived person, who died at the age of 122. It nearest competitor is the Palace Bulb, which is 106 years old and now resides at the Stockyards Museum in Fortworth, Texas in the US.
