A life indicator is so designed that an electric current flows to a light emitting diode utilizing a battery as a power source when two electrodes are electrically connected. The two electrodes are so installed as to be electrically connected by passing water through a water passage communicating with an objective equipment, and the discharge life of the battery is set equal to the service life of the equipment.
