ABSTRACT OF THE DISCLOSURE An electrical circuit tester having hot, neutral and ground terminals adapted for connection to the hot, neutral and ground contacts, respectively, of a household electrical receptacle is provided with three glow lamps and three resistors connected in series with the glow lamps, each series combination of a glow lamp and a resistor being connected between a different pair of the terminals. Each glow lamp is shunted by an associated shunt resistor, the shunt resistor serving to lower the voltage across the glow lamp when full line voltage is impressed across a series combination of that glow lamps and any one other glow lamp.
