Adolphe Chaillet's "Shelby" Bulbs

These lightbulbs, produced by Adolphe Chaillet and the Shelby Electric Company, are used to light the Warehouse. The lightbulbs never burn out, but can be broken.

Origin
The Shelby Electric Company manufacturer of the famous Centennial Light, a light bulb produced in the late 1890s that was donated to the Livermore-Pleasanton Fire Department in Livermore, California in 1901. It has burned continuously to this day.

Notations on the Livermore-Pleasanton Fire Department historical section based upon the lightbulb state that it is the construction style and quality which gives the Shelby bulbs their longevity, not as an anomaly.
