Reverse lights arnt working?

well the back up lights on my 1978 f250 havent worked since i got the truck but now its time for a new inspection and they need to work in order to pass. when i put power to the wires with a test light running from the battery the lights do cut on but that is the only way i could get them to cut on. I have tried replacing the NSS with a used one my grandpa had and still nothing.

does anyone have any idea what is causing them to not work or what i could do to fix them??

Well a used one could be bad also. Is there power TO the switch?
