An ignitor and ignitor monitoring device is provided which is externally and detachably mounted to a high intensity discharge (HID) luminaire. The ignitor monitoring device provides a visual indication of whether or not the ignitor of the lamp in the HID luminaire is functioning. If the lamp is not on and the indicator is activated, sufficient open circuit voltage is present to operate the ignitor, the ballast in the luminaire is most likely functioning properly, and power is present to operate the luminaire. A service person can assume that he lame is defective and can replace the lamp as a first attempt to correct the problem with the luminaire. If the lamp is off and the indicator is also not operating, the luminaire is not operating for any of a number of reasons such as a defective ignitor, a defective ballast capacitor, a defective lamp or loss of supply voltage from the power source. A service person can replace the ignitor in a first attempt to repair the luminaire. Replacing the ignitor is the simplest initial repair option since the ignitor is externally mounted on the luminaire.
