Abstract:
End-of-life indicators for lamps, and methods for indicating the end-of-life for lamps, are provided. A solid state light source end-of-life indicator is located on the exterior of a housing of a lamp, and includes at least one light emitting diode. The solid state light source end-of-life indicator emits light at the end of the life of the lamp. The solid state light source end-of-life indicator may emit light upon receiving an end-of-life signal from an end-of-life detection circuit, which detects when the lamp is at an end of its life.
