Abstract: The present invention is directed, in part, to an apparatus and methods thereof that effectively allow the testing, detection and identification of non-functioning light bulbs used in typical string lighting assemblies set up in series. The invention creates a circuit that determines whether there is a damaged bulb in holiday or occasion lighting assemblies by employing use of a power source, such as for example, a 9-volt battery, two wire leads and two terminals that create an electrical circuit when the terminals are attached to the lighting assembly wiring by means of the terminals. When the test kit is attached and the bulbs fail to illuminate, a user is thereby informed that a bulb within that series is damaged or otherwise non-functional. By further narrowing the number of bulbs tested, the kit allows the user to identify the damaged bulb and replace the bulb quickly and easily.

Abstract: A method of locating a defective bulb or socket in a light strand. The method includes connecting an electric power connector interface plug to exhibit an electro magnetic field thereat for checking its wires for operability of a fuse situated in the interface plug, and traversing an electro magnetic field detector along the non-illuminated bulb/sockets starting with the first non-illuminated bulb/socket closest to the interface and continuing in succession down the light strand until a non-illuminated bulb/socket is located that exhibits an electro magnetic field detection test opposite than that of the previous electro magnetic field detection test. Thereby identifying the non-illuminated bulb and/or socket with an electro magnetic field which is directly adjacent to a non-illuminated bulb and/or bulb socket that has no electro magnetic field as defective. If only this bulb is defective, its replacement will illuminate all bulbs in its circuit.
