Abstract
A portable, battery-powered combination probe search test light, test lead, and continuity tester provides a selection of modes of use for illuminated and non-illuminated search and continuity indication, in a simple circuit; according to needs indicated by push-button switches, continuity of a circuit to be tested may be indicated by illumination; in a further mode continuity is indicated by illumination of a dimmer light; these modes provide for testing the lights individually; two flexible leads with clips and a novel housing-mounted pivotal probe in selective combination provide contacts for the versatile modes of testing and for charging the battery either, with or without, illumination indicating charging.

A system for continuity testing having:
- a housing, a battery with first and second electrodes in the housing, a first lamp with first and second terminals, first means for switching, means connecting the first lamp first terminal through the first means for switching to the battery first electrode, a second lamp with first and second terminals, a probe assembly, including a probe;
- means connecting the probe between the battery second electrode and the second lamp second terminal 90, a shunt circuit between said second lamp first and second termials, second means for switching, connected in series with said shunt circuit;
- first and second leads with respective contacts, the second lead connected with the first electrode, and the first lead connected with the first terminal of the second lamp.
