The only reason for a four star is the gasket that was with it was junk other than that it fit like the oem one

I was a little hesitant about the seal on this but it seems to be holding up just fine through the couple rains we've had since installing it. I'd recommend this one over the cheap ones on Amazon. 1A Auto has never disappointed.

Great product. I have a 2012 Sierra that developed a leak. I replaced it with this 3rd brake light and it solved the issue and it's been tested in the PNW rain. Great product so far.

Was skeptical at first but the reviews made me pull the trigger on this product. Overall super pleased.. looks well made and pretty close to the oem version. Everything fit well and gasket fit snug and I ran the hose on it for a couple minutes and no trace of water inside the cab. Can't beat it for half the price of most models online.
