What he said. Just get a new tail light assembly.

You are best to just replace the entire tail light assembly for a new one. They cost about $6 - $10 at your local RV dealership parts shop.

I just noticed your camper is a Keystone Passport. You'll have NO problem getting a new replacement tail light fixture with the tabs. Keystone uses the same one on everything, and pretty much, so does every other brand too.

This looks like a simple solution at low cost:
