Trailer's light

I have f350 2008 super duty 6.4l
The signal light &the brake light are working fine on the trailer but the trailer's light does not turn on.
I checked all the fuses,the wires all are fine.
What could be the problem
Any suggestions?
Thank you in advance

sounds like a ground problem to me. I would hook at jumper from truck to trailer and see if that helps.

I would also test for power at the 7 pin connect for the trailer lights.

I know you said you checked the fuses but to be clear you checked the fuse on the drivers wheel well under the vacuum pump correct? It is one of the large square fuses with the clear plastic top. I had the fuse blow when I had a short on my travel trailer, it took me a while to find as I was looking in the wrong fuse block.
