For anyone interested. This is the AH 3rd brake light. Skip g and go h. This gasket isn’t the same foam anymore and it’s substantially taller

This is the one I purchased \/. Do yourself the favor even if you don't have a leak, just get the new one and replace it. It looks like it'll sit way up from the cab roof before you screw it in, but it has a positive seal feeling when screwing it in. going to water test it here shortly.

BTW: I water tested it for over an hour and no leaks. just leaked 2 days ago from a rain storm with the old one, so I think she's water tight again. Even used a scope to watch behind the headliner. no drips!

Do you need to purchase the whole assembly to get the gasket? That's what it looks like.

That would be my guess, yes. the mounting surface appeared wider also, like they changed the light mold to fit a wider gasket.

Looks like closed cell foam, like marine gasket that has been used as a diy.

So they admit the previous gasket wasn't sufficient, yet if you're out of the 3/36 warranty, and have a leak due to the original gasket, you get to pound sand. Good times.

On my 14' RaM 3d brake light started to leak when the truck turned 2.y.o, exactly the same happened with my 21', so seems like no improvements from FCA. I got a habit in 2016, every time I am leaving carwash, I check my back window from the cabin mirror. Good gasket with silicone normally fixing the issue for 6+ years, but considering possibilities of the cracked frame, still makes sense to check. Many people finding this leak, when the truck is almost flooded.

I get it but we should not have to check for leaks everytime we get in our trucks. That is why I am dumping my POS soon. I'm tired of it, I want to start it and go.

I like my RaM very much, I was with f150 before and not even thinking to switch back to Ford or any other brands.

Good lord no! I would never switch back to the F150.

If I had a choice and was going to trade, I'd trade for a Nissan Titan Pro-4X

Just purchased my 2021 3 weeks ago and today I noticed the slightest amoutnt of water behind the interior plastic trim on passenger rear corner of the window. It looked a little damp so I pushed on the trim and that's when a few drops of water came out. I couldn't find a trace of water anywhere else and my window frame isn't cracked. Could the 3rd brake light cause a leak all the way at the corner window or would it be more than likely the window itself?

Also attached pic is what the 3rd brake light gasket looks like. Looks like the upper gasket is coming loose. Regardless if it's the cause of the current leak I'm going to by the new version since it's cheap.

I still have about 10 months of warranty left but spending $23 is easier for me than dropping off at the dealer. But if it still leaks I'll take it in to see what they say.

The new and improved light came in today and the seal definitely looks much better. Unfortunately I still have a small leak after putting the new light in. So off to the dealer I go to see what they say it is but my guess is that I'll be getting new window.

So is this the new gasket used in newer trucks?
Yes. this is what comes on the 2022+. Works on 2019+ though without issue. At first it feels like the light is going to stick up. once you torque it down though, it's flush.
