3rd Third Brake Light Seal Gasket Compatible with Chevy Silverado GMC Sierra 2014 2015 2016 2017 2018

Fits exactly as It should. Very thick, thicker than OEM seal.

Used this to fix the seal on my 2015 GMC 1500 Sierra. Fit great. I also used some caulking just to be such it doesn't leak again! But the instructions do say it should work without any caulking.

This is a great seal for third brake light, it has great sticky adhesion and will not come off, it’s thick and works great, make sure you peel the old gasket off first and clean it up then apply this one to the light housing, works like a charm and well worth the money

Fits 2014 to 2019 Chevy Silverado and GMC crew cab trucks came super fast gasket is thicker than what I'm used to still run a little bit of silicone on around the top edge of it. Highly recommend this one will update in three months but so far I've had it for two weeks washed the truck no leaks.

Worked as a perfect replacement on a 2014 Silverado.
