Quick video breaking down how to fix a leaking 3rd Brake Light on a 4th Gen (2009 or Newer) RAM truck. This is a very common issue with RAM 1500, 2500, and 3500 series trucks and can lead to major water damage in your interior if you let the stock 3rd Brake Light gasket deteriorate. In the video I outline a quick, cheap, and simple fix so that you won't have to worry about water leaking past your 3rd brake light.
UPDATE: After you do this fix, and after you've reinstalled your third brake light be sure to go out and retighten the screws that hold the third brake light in place. Since the gasket can shrink down a little bit after being installed it never hurts to double check and make sure things are nice and snug and secure. I went out and re-tightened mine down after a day or so.
UPDATE 08/11/2021: Had a few questions about how my gasket is still holding up after 3-4yrs of being on my truck. It still doesn't leak. I actually need to change out the bulb as it burnt out, so I'll be having a look at the gasket to see how it's held up over this long period of time. I would say almost 4 years without having to replace it is well worth how cheap it was to do this simple DIY fix, and I have enough material leftover to easily do another application if need be. Thanks for watching the video guys, I am extremely happy to see how many RAM owners this has helped. Thank you for all of the kind comments, it's very much appreciated.
