In 1901, when the tiny bulb was first screwed into place inside a so-called hose cart house, it cast its light on a simpler era. Back then, horse-pulled carts carried water to fires. The bulb burned day and night, hanging at eye level from a 20-foot cord. Its job: to break the darkness so firefighters responding to calls wouldn’t have to fumble to light the wicks of their kerosene lanterns. Manufactured by the Shelby Electric Co. of Shelby, Ohio, the bulb soon outlived its maker, which closed in 1914.
