With all the recent rain, I've noticed that the center dome light is collecting water and dripping.
i have a 2021 mega cab with a sunroof, and I checked the drains; there are no issues.
I replaced the third brake light with a better aftermarket light.
Are there other common areas leaking on the 5th Gens that would pool to the center dome light?
Thanks
Michael

Most likely, it’s the gasket behind the light.Originally Posted by DrMarrs
It’s a very common issue with these RAMS.
Aftermarket lights, a lot of times, don’t fit as well as OEM lights.

This one is the upgraded Mishimoto which had a much nicer seal than the stock.
Also, the leak was there prior to swapping out the third brake light fixture.

I'd still pull the 3rd brake light and check the seal.
The only other possibilities are the sunroof and cab seams.

Thank you.
I will take another look and investigate.
Can you please share what people are doing to seal this third brake light so I can be prepared to fix it upon inspection?
Thank you

When the dealership replaced my third brake light because of water intrusion, the new light came with a thicker gasket.

I use severe-duty exterior clear silicone from the hardware store.
I run a nice thick bead around the opening on the truck and carefully replace the light housing.
This was how the dealership fixed my first 2 RAMS.
I had to do this on my '19 this week after having some water show on the seat last weekend.

I ordered the gasket from @Geno's Garage, and I’ll try that first.
Then, I’ll move on to the silicone.
I worry about stripping those two cheap screws holding the light in place.
