Question Condensation in Headlights?????

Okay fellas and ladies?

My son and I were putting in new GE Nighthawks and I noticed that the passenger side headlight has condensation in it.

How do I take this out??????? Can I take this out?????

Any suggestion will be as always greatly appreciated.

God's blessing and grace for a fast car, wonderful children and an understanding wife.

You can probably take the light housing out and put it in the oven at ~200° for a while to drive the condensation out. When you put it all back together, be sure that the extra cap on the rear of the lamp seals properly.

Below is a pic I pirated from Bill Ball's headlight swap page showing the white plastic "extra cap" I am talking about:



The pic doesn't show because there is a '&' character in the filename, an html no-no.

If you have the big lights then H2O may be leaking in from around the area where the glass seals to the reflector if this looks suspect you can fix it by using blue tape and carefully taping around the seal with about 1/8 inch to the side of the seal then do the tape on the other side of the seal get some Yamabond,and with a small amount spread it onto the light housing work all the way around the light at the seam you can smooth it with a wet finger, not too much sealant as it will start to run after it sets up for about 10 mins carefully remove the tape and you then have a very fine sealant line around the light it will dry to a semi permeable seal and the light should stay dry unless your bulb cover seal has been comprimised

The moisture can be removed by blowing dry air into the lens/reflector cavity for a while. You can also seal the bond between the lens and the reflector by using the flowing silicon sold for windshields. I've used that on a couple of these H-5 lights over the past 6-7 years. Never leaked again.

What Gary said.
Hairdryer. Clear silicone.
I didn't quite smooth the silicone before it set so it looks a little lumpy if one looks closely. Mine leaked at the bottom of the lens/reflector seal.
Or the part that gets most airflow when the light is in the down position.

spraying wd40 around where the bulb plugs into the lamp can also improve the seal and fix the problem.

before you do that check the light for cracks or holes that could let moisture in

I've always wondered about this as well. Mine has a very light haze (not moisture) that makes it look old. I think the only way to remove this is to actually wipe the inside of the lens but it appears that it can't be accessed. If the bulb is pulled out does anyone know if a long cotton swab would be able to reach the lens to wipe it?

or just drive the car with the headlights on all the time. After a week it will be gone. The condensation builds up if i dont drive the car. But when i was driving it all the time it cleared up. The bulb puts out enough heat where it will get rid of it....eventually.
