Someone has spliced a portion of a quarter panel over the original panel.
Your tail light assembly was fastened to the quarter panel, with pop rivets, from the inside of the sheetmetal, when the trailer was manufactured.
Instead of removing the quarter panel, or tearing out the inside of the trailer to get at the tail light, you can reinstall it by adding some vulkem, to the back side of the bezel, then fastening the bezel to the metal with some plated sheet metal screws. When the vulkem cures out, it will help to hold the bezel in place.
Unfortunately, the screws will have to stay in place.
