Next year (June 18th, 2013) is the 111th anniversery of the
still-burning Shelby Light Bulb at the Livermore (CA) Fire Department.
The bulb has been continuously burning for over 110 years! And, for the
last 20 years, every Fire House Chief has been scared that the bulb
would die on their watch ;-). It even has a webcam.

Incidentally, 110 years is nearly 1 million hours of operation.
