Moisture in tail light
Today, I noticed some moisture in my drives side tail light lens. Has anyone had an issue with this? Of course I'm a few months past the bumper to bumper warranty.

One way to get the moisture out is to remove the tailight one evening. It's just two screws if I recall. Unplug the bulbs and bring it inside. Get an old pair of nylons from wifey. You want to make a bag that will fit in the holes of the bulbs in the tail light out of the stockings. Not too big, but large enough to fill with rice. Tie off the top with string and leave the string long enough to tie a large washer or pencil to the bag doesn't get trapped into the housing. Let sit overnight. Rice should absorb all the moisture in the light. Once all the moisture is out. Look for a seam or crack letting it in and seal it up with silicone tent sealer. It's UV resistant and a stronger type glue. You can also buy a small tube rather than a caulk tube type canister. Just my advice. Good luck.

Why worry about it unless it's literally holding measurable amount of water. I've seen moisture in all my Super duty rear lights at the bottom after washing the trucks never gave it a thought.

Call me crazy, but as much as these trucks cost, I expect them not to leak 3 months after the warranty expires.

Not causing any problem yet. I just noticed it after we had 4 straight days of rain. Here in FL, stuff will start to grow in there if I let it go too long. Probably will work on it this weekend.
I will report back when I figure out where it's leaking.

You'll have fish in their in a week... (I know, I lived there for a long time)
The heat from the bulbs in my taillights burn off whatever builds up in mine.
FWIW, GM gave up on keeping moisture out, they have holes in the bottom of their taillights. No saying you should drill holes in the Ford ones though!
Might show that to your dealer and see what they say.

Lee,
I know this is a pretty old post, but I have a 2015 F250 with almost the exact same problem. The moisture in the clear portion of the back-up light in my passenger tail light is nearly identical to your photo. Did you figure out a solution to the moisture issue? I tried to silicone the edges of mine but it didn't resolve the issue.
thanks!
Randy

Randy,
Sorry, but I ended up trading this truck in for a 2016 about 3 weeks after this thread. I never came up with a solution. The trade had nothing to do with the moisture.
