Abstract

A multipurpose light apparatus (100) is described for use with an electronic device (400) for indicating the occurrence of an event and providing a programming path for the electronic device (400). The light apparatus (100) includes an indicator light source (104) for indicating the occurrence of an event and a light adapter (102) having a plurality of terminals. One of the terminals (112) of the light adapter (102) is coupled to the indicator light source (104). The light apparatus (100) also includes a light sensitive detector (108) coupled to a second terminals (114) of the light adapter (102). The light sensitive detector (108) provides the means for receiving information to program the electronic device (400).

Claims
