    Water in headlight? No visible holes or cracks?

    Water in headlight? No visible holes or cracks?

    How about some ideas on the cause of this problem?



    This is the first new car I've owned and as such all my previous cars have had the traditional old-fashioned headlamps. I noticed after washing the Pilot the other day I noticed water in my headlight cover?

    I inspected very closely for cracks, chips or holes and found nothing? does this mean a gasket is leaking? What's the fix? Take it to the dealership or is this something I can fix by visiting Autozone?

    I had the same issues on my '96 Grand Prix GTP, only in the tail light. It did turn out to be a gasket.

    That almost looks more like condensation rather than water that infiltrated from a car wash session. A gasket issue could still be the cause though. I get a little bit of condensation in my fog light lens covers on the GTO. I was a small amount and I forgot to tell the dealer service dept. that when I had my tires replaced.

    I'm no expert here, but could it be condensation forming inside because of a difference in temps?

    Maybe when you washed the car it cooled the outside just enough to cause condensation to form on the inside?.....Is it on both headlights?

    Oooppps.......Ramair beat me to it.

    recently that was happening to mine ( due to a crack )

    I ignored it then it started to fill with water after a good rain storm.

    now the low beam burnt out, most likely it would be the gasket
    separated slightly from the light.

    It cannot be condensation inside unless the seal is broken somewhere.

    Put simply, you do not get any condensation unless water is sealed in. Assuming it was factory sealed and done right, that should never happen.

    Sence there is no chips, cracks..., I am thinking you need to check the reverse side. You probably need a gasket.

    If I were you I would take it to the dealer and get it fixed under warrantee. Just make sure you leave water in for them to see. However, let them know you will mkae sure they get all the water out! Honestly, they need to dry it and also use some compressed air, a heat gun, or a hair dryer... something to ensure there is no water or water vapor in there or you will get a little condensation when it is cold.

    I am sure you will get this fixed.

    Most headlight casings have a drainage hole to remove condensation and allow air circulation. When my sister's Volvo needed a headlight lens replaced, she bought one on the internet b/c they are so expensive (nearly $300!) and she could save some by buying it this way. Unfortunately, the casing didn't have a drainage hole, and when I wash it, the same thing happens and it looks like your picture. It kind of looks cruddy, but I asked the guy at the dealership and he said it is really not that big of a deal. It won't make the bulb explode or anything, and the water will go away eventually, just more slowly than if you had a drainage hole.

    The headlights lens assemblies are ventilated to compensate for atmospheric pressure changes. Some condensation will form on the inside of the lenses which should evaporate with headlight use in about 30-120 seconds depending on conditions. Think of it like your front windshield when it gets fogged on the inside...Basically it's the same concept.

    If the headlamp lenses weren't ventilated...The pressure changes could crack the lens and/or blow the bulb!


    not from a pilot but appears its a common thing with hondas

    Howdy Mike,

    Looks like a seal (around the bulbs) or a gasket (if it's a two piece light casing), that has failed, or is not tightly inplace. Since it's a new car I'd let them take a poke at fixing/replacing it first (as it very well could be a cracked case or a bad seam). And do not allow them to tell you that it's "NORMAL" cause it ain't!

    Otherwise the "fix" would be to check out the rubber seals around the bulbs, as well as checking out the seams around the housing to make sure there are no gaps or cracked glue along the seams. If you find cracks in the seams, a little plastic safe, silicon caulking should do the job, after you get the inside dried of course. You can remove the bulbs and use a hair dryer or vacuum cleaner exhaust to get it dry inside.

    If it were me, I would get them to replace it.

    The headlights on my new V50 had some condensation in them when I got it last Feb(new), but I haven't seen any condensation in them since. They must have washed the engine carelessly or something. I have washed the engine several times after that and no condensation.
