Under the hood of your 2011 Dodge Ram there should be a 20 amp fuse for the trailer running lights. It is a fairly common problem with your generation of truck that fuse ends up blowing.

There should be a legend on the fuse box somewhere that details where all the different fuses are. Use that to find the correct fuse and replace it.
