And Dodge / Ram has had this issue for how many years now
It's amazing how such a simple gasket can cause so much damage on a $50,000 Ram 1500 if you don't discover it right away and fix it
Dealers will install a new light using the same old cheap gasket that is attached
And when that fails again they get the silicone out , just great when you have to replace burned out bulbs
Just blows my mind
Anyways I went with a stick adhesive rubber weatherstrip seal from soft seal
Just had to play with different widths and thickness
