3rd brake light

[Chevytruck98]

So my truck had a led 3rd brake light on it when I bought it, I've read that they leak with out the original on it. My question is I'm looking to go back to stock and was curious if the rc and extended cab light lenses where they same as with the gasket and the base the holds the lights. Any help would be appreciated! Thanks.

I have no idea, but did have to replace the one on my suburban. They aren't cheap either.

Short answer, no.

Long answer... There were two different factory 3rd brake light assemblies for GMT400 pickups. One for standard and crew cabs, one for extended cabs. They don't interchange. Might bolt up, but the curve of the roof is slightly different and the gasket won't seal properly. Both are discontinued though. If you want a factory 3rd brake light for a pickup you're going to have to find one used.

The SUVs used a completely different 3rd brake light assembly from the trucks.

Yea I figured. Thanks I just wanted to confirm. If any body has a picture of a rc 3rd brake light original would appreciate it.

I'd think it'd be easier to seal the one you have wouldn't it? Silicone ought to do the trick and be invisible.

It's GM part numbers 16520063 (Lens) and 16522433 (Housing).

This listing/website is in Brazil and they won't ship to the USA unfortunately, but there's some pictures.

This is what I did with my Anzo LED 3rd brake light assembly. My XM antenna runs to the roof through that opening, so the gasket would leak just a tiny bit in car washes. I took it off and ran a small bead of silicone across the top edge then reinstalled, it's been fine for years.

I had to replace my original because the lens cracked around the screws unfortunately.

Pretty sure it's still in the parts pile somewhere though...

A few years back I replaced the base for my 99 crew cab third brake light. It was new old stock off of ebay, still in the package.

Even with a new one I wouldn't trust it to not leak.

So just like with the old, I use a strip of wide vinyl (electric/black) tape all the way across the top, covering the gasket. The tape adheres well to the the cab / paint and the top part of the lens.

Mine failed when I had hair, are they required for a safety inspection in certain States?
