Default Tail light condensation

Any one else having problems with tail light condensation? I took my car to the dealership about a month ago and they said that the tail lights in these cars are vented and condensation build up should go away...

Well there is about a quarter inch of standing water in my drivers side taillight.....I think I was lied to -.-

I had a full blow terrarium in the left tail light. It will be replaced under warranty this Saturday. They are also replacing the right's gasket. I'd tell them to fix it or find a better dealership.

Had condensation in both taillights and had them replaced under warranty. A few months later, started to see slight condensation again. I bought some thicker gaskets and sealed the gaskets to the taillights with some weatherstripping silicone sealant. No issues since. If the condensation does come back, I'm thinking of using some black waterproof tape to seal up the top of the taillight where it meets the body so that water doesn't go behind the taillight at all. The black tape should make it unnoticeable and is easily replaced/removed if necessary.

Yeah supposedly the 2014/2015 FT-86 were given thicker gaskets, but I think someone refuted that. I'm not sure. I know mine were COMPLETELY gunked when I took them off to put on the TOM'S. I get some condensation with the TOM'S, but not nearly as bad as the stock taillights. It's just how that drainage works when it's raining or car is washed, it goes right through (around) the taillights and the gasket just sucks.

My 2014 had a slight buildup on delivery. It got worse after a few days, but I had Tom's waiting to be swapped so I never bothered attempting to fix. Tom's has never had a problem at all even when being washed with high pressure system every time. I never compared the gaskets but I guess that would be the answer

This was probably the single most common issue with 2013 BRZ's. I personally had mine replaced/gaskets swapped at the dealer. If you check FT86Club.com there's a huge thread about it, including the TSB that you can point out to your dealer.

Honestly, all dealers should know this by now, it was that common.

I just had one of mine replaced today at the dealer. They looked at the standing water in it, took a pic to document it, ordered a new one on Friday and put it in on Monday at my convenience. Took about a half an hr.

The real fix would be new updated seal and lens. It solved the issue.

First time they replaced with completely new tail light but still have the issue after few months.

Finally replaced the seals and lens and now issue fixed

My taillights were doing pretty good until about last week. Now they're collecting water and fogging like crazy...

For this issue there is a tsb, if I remember correctly it has to do with bad gaskets and over torqued bolts

The new gaskets still yield the same results though. I just cleaned out my taillights. Basically water is getting in air holes that are part of the taillight mold/design. I drained them and dried the gasket. My assumption is that when the gaskets get overly wet and are no longer able to absorb the water, the water find it's past the gaskets and gets into the designs holes in the lights. No clue what I can do about that since it seems there's less water build up when the gaskets are dried out compared to when they're soaked. My seal has help up just fine around the edges, so water isn't getting in between the the gaskets and taillights, but is getting in between the gaskets and body of the car.

Did you try to seal the gaskets to the tail light assembly with some sealant? I haven't had any issues since doing that. Some others on the other forum have used anything from tape to putty to fill in the top of the tail light and the car so that water streams over the tail light and out the back instead of being routed between the light and body.

Yeah, I added the sealant that ninjagaskets sent and it's still on there holding up pretty well. Yesterday I took my car to a bay wash that had a blow dryer. I turned the taillights upside down (lens facing up) and let the water drain out. Then I blasted the holes with the dryer. Nothing happened to the condensation inside the lenses. I blasted around the edges and in all of the holes, and tried to notice any reaction to the condensation in the lenses, but nothing moved.

However, there was more water that seemed to come out from underneath the gaskets from the innermost edges, not the outside edges where I put the sealant. The innermost edges are supposed to be clear from the outside elements. Something in the assembly is routing the water incorrectly and allowing them to pool at the bottom and create condensation. The lenses were clearing up after I drained them, but when I looked at them this morning they were all fogged up. I'm assuming that's from the moisture in the air because of the cooling at night?

While cleaning them I noticed a screw in the corner of the assembly that I presume helps hold them tight. I'm thinking I might bake the taillights in the oven and open them up to see if I can reapply some sealant within the assembly. Hopefully I don't jack up my $500 taillights...

When I first got the taillights in December of 2013, I only ever got slight condensation. Then it got worse, but never this bad. I purchased the ninjagasket kit and the condensation went away almost 100%, but then the last 6 weeks or so it's gotten worse than it's ever been. Even my stock taillights never had this kind of issue.

Your experience is the one reason why I've not purchased Tom's or any other tail lights. My stock units don't fog or get condensation right now so I don't want to touch them at all. Hope you're able to find a solution.

The reason I changed up was because my stock ones fogged anyways, and they were ugly. I've really considered the Intec taillights because by design they can't fog, but some think they're rice. I do care what other people think because the general populous has to see the exterior more often than I do.

Sure. . if only they didn't have melting issues. Seems to be only with the clear units though.

I sold my TOM'S. Clear, USDM. No melt, but they retained water way worse than any stock taillights I've seen on the Twins. I've since had JDM OEM taillights and they've been great. I miss the TOM'S because they look like OEM designed lights, but their quality did not match their asking price.

The new OEM tail lights are nice, but I'm not willing to pay ~$800 for a pair. I did the gasket mod on my stock lights and that stopped all condensation. Just not worth it to me to muck around with them and end up with condensation or other issues.
