How to PROPERLY Seal Headlights from Moisture & Condensation 

🇮🇹🇵🇹 in Canada we can fix anything we put our minds too. This day and age is a perfect time for this generation to have such an extremely useful tool such as RU-vid at their grasp to learn everything from repairs to cooking. Thank you for the videos. When my father came to Canada as a young teen from the Açores he had to teach himself by reading countless books on plumbing, electrical, automotive repairs amongst other things. We were always told as kids until today that being knowledgeable enough to fix even the basics around the house and car is a priceless gift and can/will save you a good amount of money in the long run.

Probably one of the most ideal videos for headlights 👍. It's so unsightly see headlights with condensation in them due to improper sealing

I used gas-powered oven with 3 pieces of 2x4s to lay the headlamp on. At 200-220F for 10-min. This melts the OEM butyl sealant, makes it soft enough to take apart the lens & housing without damaging anything. Clean the mating surfaces by re-heating the housing and tracing the valley with a flat blade screwdriver & utility knife (I use OLFA or NT CUTTER brand). A perfectly sealed housing actually builds up heavy condensation. The temp difference between the inside & outside of the headlamp causes condensation, especially on HID or LED bulbs that do not get as hot as halogens. There should be breathing ports on the backside of the housing to equalize the temp difference and release excess pressure if halogen bulb is installed. I have 2004 Acura TL, and the passenger side is notorious for building up heavy condensation. I take it apart, clean the inside, apply wax on all possible surfaces (wipe clean of course), and after rebuild is done, I install some desiccant packets. This usually resolves condensation but cannot completely eliminate minor fogging, as it is just a nature of modern headlight housings. I expect more R&D at parts suppliers do that we do not have to take headlamp housings apart. P.S: For 3G Acura TL, the HID ballast has some gaps at the connector that can allow moisture to enter & short circuit the ballast. Fill every gap with silicone sealant to keep water out (a heavy condensation eventually finds its way down into the expensive ballast.....roughly $50 at Amazon but a dealer wants $300-$500 for one).

Awesome video, I have this issue on my vehicles as well have seen on many other vehicles.

Great in depth, easy to follow how to, thanks Milan, great job 👍👍👍

I love your videos. Your enthusiasm and positive attitude are contagious - GREAT JOB! Take care my friend. ;)

Many folks use the oven. 140 degrees for around 5-15minutes, depending on the oven, fan assisted needs less time, less heat. It works btw, i've tried it, oven gloves required etc.

Love this video! I would have liked to see you disassemble the headlights though.

The canadian is strong with this one!

Butyl is also good for sticking on your tools to pick up bolts in hard to reach places. You can stick it on the end of Torx sockets or in normal hex sockets and it will pick up whatever you need it to.

From one of your last videos, when you were installing the taillights and you thought you liked the chrome surround to match the crome on the headlights, door handles, etc. it sounded like you didn't want to go with black trim. But, the headlights look so much better in black and I feel that you might be able to find black door handles and change out the taillight trim to the black as well.

Well made video man. Thank you. Im doing the same w my mecedes xenon headlight it leaks. I used my oven, 200 degrees for 16 mins. Thank you this really helped

Great video! still waiting for manufacturers to design their headlights with some kind of fastener capable of preventing leaks instead of dealing exclusively with messy, sticky substances

Awesome thanks 😊

Explained very well.

NICE ONE! and a good demo! Thanks 👍✌✊ UK

You should remove the original glue on the headlight

Revisiting this video after watching it a year ago when you uploaded it. I did a similar mod. A year later the black plastic closest to the top bulb burnt/melted a bit and looks horrible: time for a redo. How did yours hold up?

Nice work bravo

Good stuff !

How do I seal my tail lights up so I don't continually get condensation in them. Ive tried using silicone on the edges but still getting condensation in them. Have any tips for me?

Shout out from South Africa bro !!!!!!!!!!!!

Absolutely thee best tutorial video I've ever came across. Good job, hope to see more from you.

I wonder if E6000 would be a good alternative. Scraping and cleaning off the adhesive, squirting a bead of E6000 in that groove.

Is it doable for R56 [with xenons] without removing headlights from the car? I'm going to replace lenses using heat gun and butyl glue.

Where did you get the led turn signal portion of the headlights?

nice video bro , keep it up

Great walkthroughs thank you! Any idea how to remove the lens from the cover on a 04 mcs?

What name of sealant sir and is it can able to buy on online thank you for video sir.

What is the little chrome door on the light for?

great instructions, going to make my son follow this an re-do his correctly this weekend. The painted cover looks really good too

Hi where can you get the Gilmore snow gun in the uk from please

Can you please do a video step by step how can put in fuction the headlights washer? I saw many videos but no one knows for sure or did not explained

ty

Nice vid bud you're killing it with the uploads

Can someone tell me where to find the description box . I have never seen one anywhere on RU-vid. Thanks

How did you remove the lense from the headlight?

Your accord is also sealed up like this right ? Dude has done a great job ...v can still c that even today his accord headlights are free of moisture

Would it be safe for me to use flex seal?

So no clamps? Just force by hand?

Do I have to remove the old butyl?

Ah.... the famous Joey mod. Also usually it’s easier to stick it in the oven at a certain temp for a proper seal. Also when I’ve done my lights I’ve removed all old butyl from the headlight ridges. Add new butyl and stick it back in oven. That’s how I did my custom headlights from my Rsx when I retrofitted TL projectors.

Pretty solid alternative versus using a oven.

Clear Flex Seal worked just fine for me. That way you don't have to worry about needing a heat gun to soften the sealant.

Hoping you can help me... I bought a 7” led headlight for my motorcycle (from Amazon) I also bought one for my father. Mine gets condensation inside but my father’s doesn’t .... I was wondering if it might overheat if I try sealing mine better with silicone... I don’t know the science behind whether or not this type of light should be airtight.... any advice?

Any change in visibility at night

So what u meant by max heat, what degree of heat are u talking about? Like what max degree should i set my heat gun to? And the speed of the fan

Can i use a normal hair blower if i don’t have a heat gun?

I want to go to Canada just to visit you lol

I though i saw how to steal headlights lmao i clicked fast 🤔🤭🤣🤣🤣

does common silicon sealer work?

Can i use silicone sealant instead???

Any easier way is to hear hun the seal first, when it’s soft then you put on the lens and squeeze together boom 🤯

👍

Dude, its not normal to leave a heat gun inside a box and run away for 8 minutes...

just use silicone sealant... as simple as that... cous it fit it more and seal small gaps and holes...

😎❤

i thought the title said steal 💀💀💀

Jesus - be carefull with cardbox + heatgun. Paper burns at +100 degrees celsius...

That butyl rubber crap will last until you leave the car in the sun !

Ewwt? 🤣🤣🤣

Half a video, show the hard part.

Just some feedback - I feel you add so many details that really don't need to be added, as if you're talking to a toddler. There are a lot of simple people out there, but even they'd know what to do. I'm guessing you do this to extend the video so it's not just 3 minutes long or something, but I find it to be really annoying
