ABSTRACT:
A combination flashlight and circuit tester is disclosed which functions as both a conventional source of portable illumination and a circuit continuity tester employing either internal or external sources of electrical energy. An improved multidirectional support enables the flashlight/tester to be attached to a stationary structure while its flashlight beam is aimed in any one of a variety of directions. Contacts and a positively actuated switch are replaceable. A battery biasing spring is hingedly mounted to the battery casing to facilitate battery insertion and removal. A neon test lamp indicating continuity of electrical circuits is removably mounted on the exterior of the flashlight/housing to facilitate observation and replacement.
