Condensation in tail lights or headlights?

j.arnaldo · 10-21-2009, 02:29 PM

...you're scaring me, dudes...I own an '04.5 350Z, and, so far, none of that has occurred, but you got me thinking here; it seems to be happening to quite a few 370s. Has anyone heard of it happening to 350s?!

Asheth · 10-21-2009, 03:05 PM

I have it too on mine its not so bad. But I will give it a few more days before getting it checked out. I just noticed it yesterday.

it happened to my friends 350 but only cuz when he put his hood back on he didnt line it up exactly right and when he would shut the hood it caused the seal the break on the headligt. since he didnt fix it right away he now has a projector bulb out in his drivers headlight lol. then he blacked out the headlights so he has to drive with his high beams at night

I would seriously doubt Nissan would allow these to be replaced under warranty...

Ummm...if there is no moisture, there is no condensation...the reason why you seal something is to totally keep moisture away from it...they don't seal to just glue...think about this, when you have moisture on glass, plastic, mirror, etc, soon after they tend to leave water residue...well, I don't think a manufacturer wants water residue on the INSIDE of covers...cuz in the long run, it may diminish the amount of light through them, and that's another "floormat" recall/lawsuit...

Well......You can't really hermetically seal the lights. Zenons make a lot of heat. There needs to be some leakage to accommodate expansion and contraction from this heat......There are expansion vents on the light. 3 on each tail and I'm sure the headlights have the same since there is more potential heat there. There's always some in and ex-filtration...

LOL...No! I actually took the pic from my buddy's Stasis Audi A3 while he did a flyby in my car, and that's a TT in the mirror. We were at a little Audi get-together out at the Tail of the Dragon....Good fun!

Here's a good "cop in the mirror" shot from the year before when I still had the Corvette......

I thought because of the Xenon they were not 100% sealed because with the amount of heat created they needed to "breath."

Yes...Those expansion vents have a permeable film at the top which allows them to breath. You can blow through them (with some effort)..

The xenons are headlamps only.

The condensation problem with the 370Z is occurring in the Taillights only. So no xenons, only LED's.

We know just the heads are xenon and both the head and tail have the potential to condensate since they are both ventilated. People have reported it in both. The point is They are not sealed. It is perfectly normal.

See "Dew Point info here: http://en.wikipedia.org/wiki/Dew_point

So, sounds like we've established that they aren't 100% airtight.

Anyone have a way to dry them out?

Mine have it too.

kenchan · 11-03-2009, 02:33 PM

just leave it out in the sun.

my G's tailamps are the same from day one. some water gets inside after washing them but it dries up in time.
