I too had a water leak onto my headliner possibly originating from the high-mounted rear brake light. I own a 2021 RAM -500 Limited. I went to my dealer after seeing posts as well as the TSB describing my similar situation. But, of course they told me that my vehicles VIN did not qualify for a warranty fix.
The dealer said that the new rear mounted light was “redesigned “ to correct this problem and that he didn’t get good results trying to “reseal” them, but I could leave my truck there and they could “run a water test to find the source of the problem,”, but that a new light would run $550, not including the cost of the diagnosis!
I read about several “fixes” online, and removed the light, took off the old gasket which appeared dried, and went to autozone and purchased auto/ marine silicone gasket material in a roll.
After throughly cleaning off the old gasket as well as the inset with alcohol, I applied the silicone gasket around the light and reattached it.
Well, it seamed to have solved the problem! I live in Houston and we’ve had torrential rains the last few days, and it remains dry…… my cost? $6.50…..
