ABSTRACT:
A circuit testing device includes a housing that is sized and adapted to securely fit into a light bulb socket. The device includes spring-loaded prongs which securely hold the housing in place in the socket until it is desired to remove the testing device. The testing device generates an audible signal when power is applied to the socket to alert a user that power is present, even if the user is located at a distance from the point of test.
