Does anyone know what those lights are located inside the bed where the tailgate latches into place. I pulled my tail lights off to install new reverse lights and checked the bulbs. The filaments are good and the connection isn't corroded, but they won't come on...ever. I asked a service tech at Nissan and they had no idea.

I have a Cargo Lamp switch inside my truck, but that switch only turns on the two cargo lights on either side of the third brake light.

Any help here would be appreciated, its been driving me nuts...and I want them to work.

Pictures would be helpful. Not following what exactly you are referring to

I think they are supposed to come on with the cargo light. I never had a T with them, but I've seen them. I would check the fuses to start. I would have thought it would be on the same circuit, but maybe not.

They are supposed to come on with the cargo light up at the third brake light. If that one's coming on and the tailgate lights aren't, it's not a fuse problem. New bulbs is a very cheap diagnostic option.

OK. I checked the bulbs they are good. I even replaced them with the bulbs I removed from my reverse lights (after replacing them with super bright LEDs from Diode Dynamics) and still no illumination.

The connections are good and I used di-electric grease to make sure.

I think I attached a picture of the lights in question (first time attaching a photo).

Any help here would be great!

the picture is sideways, but here it is!

As Carbeaux said, those are the tailgate cargo lights that should illuminate when the cargo light switch is turned on. Normal function is for them to come on at the same time as the cab-mounted cargo lights, which are located in the third brake light housing.

With the cargo light switch on, are the overhead (cab-mounted) cargo lights illuminated? If no, check the cargo light fuse and the cargo light relay. If yes, double check the tailgate cargo light bulbs for contact at the socket. Do the sockets have a good ground?

Do you have voltage at the tailgate cargo light sockets with the cargo light switch turned on? If yes, and the ground is good, it's back to suspecting the bulbs, even though you swapped them. If no voltage at the tailgate sockets, but the fuse and relay are OK (ie, the overheard cargo lights illuminate), continue troubleshooting wiring paths to the tailgate cargo light sockets.

The info on the cargo lights and wiring diagnostics are in the "Interior Lighting" (INL) section of the Service Manual (at least the 2014 version).

Hope this helps.

If you want to swap the fuse, it's in the panel in the cab, under the glove box. It's labeled adaptive cruise cont./cargo light.

the over head cargo light do come on when the cargo lamp switch is on. Im not sure about the ground, everything looks pretty factory behind the tail lights. I have not checked the voltage, but i guess that will be my next step after checking the fuse.

Any idea where the ground is for that wire bundle?

I'm thinking that if the parking/running/brake lights work, then the ground is probably fine to the tail light assembly right? I'd trace out the wiring like dreep said to see if you have a corroded or broken wire where the two wires from each side come together.
