Received from an estate sale, unfamiliar with items and how to test, the previous owner cut a slit on both the injector and tracer so he didn't have to open them for the battery I'm thinking, i put the connectors back in both.

Micronta signal injector  #22-4032 does light up when red button is pressed. battery's not included. may need tape to hold 2 pieces together.

Micronta signal tracer is untested, has tape on the body and  previous owner engraved his name, none of the included wires are original

both come as shown, see pictures
