Headlight condensation

My headlight has been getting a lot of condensation the past couple days and now my headlight went out. Is there a way to seal the headlight better or do I just need to buy a new one.

How is the water getting in the first place? Did you change angel eye bulbs and not close the lid correctly?

Blow with a hair dryer hot air in the housing and the condensation will be gone in no time .
Check housing sealing and check if the housing is closed properly...

Is there a video that shows the housing and seals. I want to make sure they are probably fitted. I used the hair dryer method yesterday and it worked. Today it came back just as bad and the headlight blew. So I'm not sure where it got worse.

If it came back that means there's still water/condensation in the headlight, most likely the water is holding at the bottom of the headlight since you're blowing it with a hair dryer. I had this happen to me and I lost my drivers side ballast due to it getting wet. If there's condensation that means that there's a crack somewhere in the seal. Could be around the headlight or the doors of the headlight themselves. I fixed mines after I took the headlight off the car, resealed my headlight and replaced the ballast. There has been no condensation in my headlight ever since I did this, not even light condensation. If the headlights are sealed properly there should be no condensation because water/moisture would not be able to get in, except from the breather tubes. The breather tubes are there so that if there is moisture in the air they can help the headlight breathe to not cause condensation. If you're constantly getting condensation your door seals may be loose or your headlight seal may be deteriorating. I know for a fact that condensation in these headlights aren't normal, because I've fixed the issue.

Most headlights have a drainage tube/valve. If that gets damaged, dirty, or blocked, moisture will build up.

We don't have drainage valves but air vents to accommodate the fluctuations in temperatures.

Only in my passenger side. I think my seals are worn down.

It sounds trivial, but make sure the little door on the fender liner is sealed well.
The one in front of the tire where you would reach through to change your bulb.

Had crazy condensation in my headlight of my last car because one was missing and during car washes (with pressure washer) it would get moisture in through that. Worth a check.

Thank you for the tip. I have never thought of checking there. For now I have an additional passenger headlight that I sent to a shop to have it sealed up perfectly so I can start from scratch.

bumping this - ran my car through the wash and the driver's side headlight has a ton of condensation in it. It's going to get very cold tomorrow, what's the fastest way to remove this without taking the bumper & headlight off? the only bulb i have easy access to is the H8, should i pop that off and just run a hairdryer at the headlight?

i think the h8 may not have been perfectly sealed, which is how so much got in there in the first place

Top hatch (i.e under bonnet) off and let dry. Yeah, some apparently use hair dryer to speed up.

I'd get it taken care of ASAP. You could fry the ballast and that would be an expensive replacement. I was getting condensation and I had them resealed locally with new covers. Now they are just like new

Friend bought a 2009 M3 about six months before I did, spent AU$4000 on a new headlight as the original was rusted beyond repair.

i got it taken care of as I mentioned.

When you say new covers, is that the top, or the entire clear housing?
