a month ago i started noticed that i had moisture in my righthead light and i was immediately saddened because i either had to bake it and take it apart or buy a new headlight. being said that, i took a hair dryer right away and tried to blast hot air into the headlight. it worked. but 10 minutes later i saw that the moisture was starting to return....* sigh * . It doesn't really help that i live in Vancouver so the humidity is naturally higher here.

As i was about to head to Acura and purchase a new headlight ( i didnt have access an oven where i could throw my headlight in ) , a buddy told me to try some desiccant.


it only cost me $2!!

i took a coffee filter, dumped a decent amount and tied the end with dental floss and i stuck it in the headlight. BEHOLD, after 1 week i notice majority of the moisture started to go away. Its been 3 weeks now , MOISTURE IS COMPLETELY GONE and i just took the desiccant out. And WOW, its rock hard
and looks like a golf ball.

i know people have done it all over the internet and there are mixed results,but i just wanted to let people know that it really does work!

 

It definitely works! Another trick is rice, uncooked plain white rice. I've dropped my cell phone into a swimming pool before, and under the screen it was all humid afterwards. 2 days in a ziplock baggie of rice, and it was perfect!

For a volume the size of a headlamp assembly, though, a true dessicant would work better as you experienced. Ever wonder why they put little packs of silica gel in shoeboxes, electronics boxes, etc...? It's because silica gel is a dessicant (drying agent).

 

Would it be possible to do this for the fog lights? What would be the best way to get it in there? And would those little silica gel packs work just as well? (probably got some lying around!)

 

Just a heads up you can go to or call Acura to see if your car was part of the recall on the headlights. They had a recall on TSX headlights b/c of condensation.

I got my new headlights at 140k miles. Saved me $600 bucks.

 

I took my 2004 in for the headlight recall..they installed some clips...I really think that the no-touch high pressure washes were the culprit...have been trying to keep away from these.

 

This is a good, temporary, fix. Once it soaks up all the moisture they can hold it will be back, then you will have to do it again. i would pull it out and bake it and re seal it. i am having the same issue on my car but its and aftermarket headlight. Stupid DEPO headlights! I am going to bake it and then re seal it.

 

I had the same issue after I openned up my headlights to black the housing. Taking the headlights off isnt hard at all, look for crazyazn's write-up and on youtube.

What i did was, I just took the high beam light bulb out, then used a blow dryer to lightly heat the interior up to hopefully remove more of the moisture.
I didnt bake the headlights, just sqeezed silicone sealant all around the seal area then smoothed it off.

I havent had a problem since

 

This is somthing I need to do, I am having the same problem.

 

Gonna try this in my headlight and fogs. They ve been fogging up sometimes when i wash the car
