Hi, my name is ***** ***** you asking about the exterior tail lights, or the lights inside the trailer?
Customer: replied 1 year ago.
the lights inside the trailer
Customer: replied 1 year ago.
The turn signals, brake lights and brake controller work, the only thing that does not work is the interior and exterior accessory lights.
Expert:  Tim Mohr replied 1 year ago.
Ok, do you have a test light or a volt meter?
Customer: replied 1 year ago.
No, A friend of mine had the same problem with his F150 when he purchased it, it was missing a relay in the fuse box, I am assuming I need the same thing since everything else works, do you have access to the diagram of a 2012 Dodge Ram and can you tell me what relay works the accessory lights for a trailer?
Expert:  Tim Mohr replied 1 year ago.
the dodge does not use a relay for this like the fords do, but they do use a fuse, it is fuse J01 in the fuse box under the hood, and usually they are not shipped from the factory with the fuse installed, is it a 40 amp fuse, can you check and see if there is one installed?
