I drove home from work today through some heavy rain. My lights (Xenons) were on and the temperature dropped somewhat. When I parked my car and turned the lights off, I noticed that both lenses over the high beam areas were fogged. I was not using my high beams.

The fog is inside the lense because I was not able to wipe it off. I don't see any apparent cracks or holes in the lights. I know that this is most likely condensation forming inside of the light because of the high humidity and the temperature change, however, I though that the lights were sealed to prevent this.

Has any one else experience this? If so how did you fix it short of dismantling the housing or having the lights replaced? The car is still under warranty.

 

no big deal, my car does it every time i wash it.

i think water gets in thru the inspection covers in the back of the housing and evaporates. it will go away, no biggie. :smile:

 

I get the foggy headlamps too, but only after I've washed the car. Maybe I'll check the bulb access flaps behind the lights, to make sure they're on...

I don't want to say, "don't worry about it, no biggie", because after all, we both paid a lot of money for the Xenon's, and seeing condensation inside them is disturbing, and perhaps lets others believe they're not of the best quality! That angers me.

Let me know if you have a solution.

 

its not doing anything, condensation on the lense has nothing to do with the bulbs.

 

The question remains. Why is there enough moisture inside the light housing to condense on the lense? This is not right. How is it getting in? It certainly isn't a good thing for it to be there, it will lead to corrosion of the contacts in time. Then light failure. Hopefully before they are out of warranty.

 

its just from the steam getting in from the car wash, i think.

it happens even on cold days with me, on the inside...

 

That's not suppose to happen. It's not right. That means that the seals have lost their integrity. Take it to the dealership and let them fix it. And...don't let them say stuff otherwise.

 

What seals? This isn't your grandpa's Oldsmobile There are no sealed beams like in the old days.

There CANNOT be condensation in the halogen or Xenon bulbs ... they are sealed

There CAN be condensation inside the plastic lens covers, just moisture got in. Just check the rubber gasket. Take a look at all driving lights, aftermark fogs, etc. There are HUGE openings in there that can let moisture in and, in fact, are supposed to be installed so the water runs out of the holes.
