Third brake light leaking please help

Well I have a leak coming from the third brake light and was wondering what can I use to seal the leak up? I already replaced it once because of a crack. Also If I end up replacing the light is there a better alternative?

If you can locate a sealant, silicone or another type, that is safe for use on clearcoat, then you can apply a bead of it along the underside of the light and re-install.

There might be...I haven't found it. People have used a variety of things. Most without reporting any damage.

I purchased a New light off Ebay and could of gotten the 3rd brake only for about $30 and it has the center lights as LED and then the factory side bed lights are reused and it just plugged straight in and looks nice. I have a picture of it in my album I think. They are Eagle Eye products and I have been happy with my purchase and no more leaks in the cab too.

Here's an interesting read on silicone in automotive uses from the guys at Meguiars:
meguiars.com: FAQ - Are products that contain silicone bad for my car's finish?

If your leak is coming from the seal around the lamp assembly I recommend the permatex clear rtv silicone. You just need to seal out water not permanently attach the lamp to your cab. I have used the motorcraft on several occasions and this appears to be very similar if not the same stuff. Could also use teflon washers between the screw head and lamp or a small amount of the silicone. 80050 permatex part number

Well I think the leak is coming from the gasket on the assembly. If thats where it's coming from do i use gasket maker or clear rtv silicone that you were telling me about?
I don't know much about sealants,adhesive and gaskets but i'm just looking for something that will stop the leak and be able to remove it in case of replacement.
Also should i remove the gasket before applying anything?

Go with the clear RTV. Also dab a little bit around the screw holes on the exterior of the light before you put the screws back in.

+1. I leave the gasket on the the lamp and apply a bead over it before putting it back on the truck.

I gave up on farting with mine, just put a BIG bead around the outside. Unless you are 7 foot tall, can't see it.

For 30 grand and up you would think the Ford idiots could keep a light from leaking. No wonder the Japs are doing well.

You are so right Toyota has never had any recalls or problems ever. I have an 04 that i got used so i have dealt with alot of very frustrating little problems but i will guarantee you that every make has their own issues.
