1. An electric circuit test device for testing an electric circuit, the test device being insertable in a receptacle, the receptacle including electrical terminals coupled to the electrical circuit, the device comprising:
a housing characterized by a longitudinal axis;
a plug blade assembly disposed within the housing and configured to mate with the electrical terminals, electrical continuity being established between the plug blade assembly and the electric circuit;
a fault detection circuit coupled to the plug blade assembly and disposed within the housing, the fault detection circuit being configured to detect a circuit status condition in the electrical circuit; and
at least one circuit status indicator assembly coupled to the fault detection circuit and normal thereto, the at least one circuit status indicator assembly including a plurality of semiconductor light indicators connected substantially normal to the at least one circuit status indicator assembly, the plurality of semiconductor light indicators being configured to emit a code corresponding to the circuit status condition in a direction normal to the longitudinal axis with a viewing angle less than approximately 30°.
