Headlight vents

[Partysan7]

Hello everyone, does anybody know where on our headlight assembly
is a vent? If there is any ?
Reason I ask this is I recently swapped my non sport headlights with the sport and now I have a little condensation inside . It has been dry outside no humid and I tested them by having them in bathroom with shower to hottest setting for 15 minutes and no moisture got it so I am thinking they might nit be breathing properly, like a clogged vent not letting heat escape.Appreciate any input.

Sorry to hear that is happening.
While I was at the dealer yesterday getting the rest of my fluids changed out, I asked my service guy about this. He had a tech come out and that tech told me that the headlamp is a sealed unit with no vents and if condensation is getting inside, it has to have a fault somewhere along the seal or a crack along the seal or elsewhere. He said the fault may not be visible, and it may not be large enough to allow water to pass inside, but it is enough of a fault to allow exchange of air and moisture to pass through.
He suggested putting a plastic adhesive or plastic-friendly sealant along the entire edge of the headlamp unit where the back and front of the unit is attached to see if that might cover the location of the leak.

Of course that requires removing the headlamp unit which, knowing Infiniti, probably requires removing god-knows-what other parts before you can get at the headlanmp unit. (that last bit was me, not the tech talking)

Best of luck and let us know how it turns out.

Thank you for your input and appreciate you asking out for me but I still believe there is a vent. I tested the headlight by having it in my bathroom w/ shower on to its hottest which created a lot of steam ,the outer lens were fogged up along with the whole assembly with tiny droplets of water all over the headlight and NO moisture got in. i believe the headlights have to be vented to release the heat from bulbs but anyways thanks.

Also it has been raining here yesterday and this morning .guess what the condensation reduced about 80%. So its just weird how it got there on a nice sunny dry day and most of it is hone on a rainy muggy day but I have another problem now, since yesterday my driver side lowbeam isnt working ( bulbs were put in brand new this past saturday. Now thats my bigger concern. Jopefully its just a bulb and not a ballast. Oh well thats what you get from buying stuff on craigslist.

Just because a tech told me, dosen't make it fact and I'm glad you're still persuing other remedies. That's exactly what I would do. Any idea is worth a try Vs the enormous price for a new unit. The idea of some sort of 'vent' to equalize temps and allow heat to escape makes perfect sense to me, too.

I read another forum about fogging lens and one individual drilled two small holes in an inconspicuous spot at the bottom of the housing to allow the water to escape. I'm pretty certain it's not a sealed unit and it could be the o ring seals around the bulbs that is allowing moisture in when the builds get hot. Remember things expand with heat so maybe your test didn't work because the bulbs were not hot.

msvara you make a great point and it made me think of yet another cause. What if the headlamp bulbs were installed in a way that they didn't seat themselves flush, or didn't 'seal themselves against the housing? Seems that might cause decreased or even increased transfer of air and moisture in and out of the lenses and coudn't that also allow for condensation to form?

I made a post sometime last year about my rear lights fogging up in the turn signal area. Thats when someone replied by telling me they drilled one or two diameter holes (on the bottom) to allow air to circulate. That fixed his problem and I was prepared to do the same but 2 days went by and it completely disappeared. It hasn't happened since.

Absolutely possible as well.

I forgot to mention that on the day my car was getting all the work done including swaping non sport headlights with sport it was a rainy muggy day and my headlights were open ( bulb sockets ) for a while, so maybe moisture got inthere that day. It disappeard now completly. But thanks everyone for replies.

Just an update, since I have a second set of headlights I took some time to throughly inspect the lamp and found that there indeed is one vent in our headlights. It is located right above our low beam enclosure.
