Condensation in the third brake light

[icegradner]

Starting earlier this week I started to notice condensation in the third brake light. I don't recall seeing that before now (1 1/2 year old now). Kind of wondering if this is something I should be concerned about, would this be due to the seal on the third brake light failing? I don't see any signs of cracks or anything like that. It's only in the clear parts on both sides.

...would this be due to the seal on the third brake light failing?

Most likely failing or the lens was not properly seated on the seal during installation.

I had a Subaru with chronic condensation in both headlight assemblies. Subaru never could fix it. But after I hit a deer, the body shop replaced both assemblies and the problem disappeared.

In most cases there is no fixing. Replacement is usually the only fix. Jeep replaced both housings in my wife Cherokee and problem solved. Best fix for the OP, if the dealer won't replace. it is just buy a new one or that $200 one Morimoto is peddling.

On F 150s the third brake light was known to leak. Causing the cab corners to rot out. It would not even stain the headliner so hard to know until to late.

It's never happened until recently, so I suspect that the seal has failed. I tired to take it off to check if the bulbs were snug, but of course one of the T20 screws was stripped either from the factory, or by someone at the dealership.
