Abstract
A plurality of lamps are connected in series. A plurality of burnout detector mechanisms are provided where one of the burnout detector mechanisms from the plurality is connected across a corresponding lamp of the plurality of serially connected lamps. When a lamp in the series enters a failure state, the burnout detector mechanism is activated providing an indication as to the burned out lamp. Depending upon the values provided in the burnout detector mechanism and the type of lamps, the remaining lamps will either enter an OFF state, or a low-light glow state.
