Is there a sure fire way to cure a fogging headlight? I've herd drilling a hole in the button of the housing can help

Does that actually work?

Stock headlights arnt even 100% sealed so y don't they fogg?

 

drilling a hole in the bottom is a stupid idea. it will let just as much moisture in as it will let out..

 

I wouldn't do it in the Bottom, more on top. You could put a breathing tissue over the Hole like the ones on the Headlights.

 

i would unseal, and reseal. Add RTV where it looks like it might be needed.

 

Do this. Very easy to do. Do it right or don't do it at all.

 

Did it right the first time lol, new Oem sealant and I even silconed the edges as well

But even stock headlights are not 100% sealed there's a hole right under where the headlight bulb slides in

 

How exactly is water going to travel UP the headlight though a hole in the bottom? Yeah.

A tiny, tiny hole on the bottom is your best bet. You just need enough to get some air movement in there, nothing drastic. You're not trying to drain the moisture out, just get some air in.

 

^^^^ that and i would re seal it

 

I can garruntee that the headlights are sealed , we had a wicked storm here a few days ago I've
Had them in for a month or so now, can power wash um fine
No issues it was just after a wicked storm so I dunno

I used new
Oem sealant and siliconed the edge afterwards

 

You said it yourself in this post:

They aren't sealed.

You have to create airflow, to keep the moisture down. If you only open one window in your house, you aren't going to get much breeze though. Same with the headlight. The one hole around the bulbs is only going to let moisture and air in. Drill a tiny hole, and it will allow the air to flow though and keep the moisture from forming.

 

Ok thanks

 

If you seal the lights 100% totally then when the air pressure within them changes the natural moisture in the air within them condenses out, fogging them. You don't want them to leak, but they do need to breathe.

 

Had the same issue with one i made iv resealed 100 times but if i get a bad stirm i get a foggy headlight

 

there's this magical thing called condensation

 

Which doesn't happen when you have air flow...

 

The last set I sealed up 100% had no issues with fogging.

I drilled a hole in bottom I'll see what happens

 

let me no if it works

 

My headlight fogged and te way I fixed it was. I took the headlight off the car and let it dry over night. Once it was completely dry I recalked the original seal and it was fine

 

:facepalm:

 

check the rubber boot on the back of the light I had some leaking issues from them.
