There is a light bulb at the fire station in Livermore, California that has been burning for 110 years. It has only been turned off for short periods, but unlike every other incandescent bulb, the filament has not burned out. The bulb burned at 60 watts when it was first used in 1901, and now is a 4-watt night light. Today, this light bulb is available to everyone on a round-the-clock webcam that updates with a new photo every 30 seconds (although it's kind of hard to tell).
