It offers LED indication and an added audible sounder to confirm correct wiring. This makes it particularly useful for checking sockets that are not easily visible or are in difficult-to-access locations. The audible indication also allows it to be used as a basic fuse finder; when the correct fuse is pulled, the buzzer stops.
