Mist Inside Head Light

[akboselk]

Hi,

recently I noticed there is mist patches inside head lamp and these happens on rainy days while I am driving with head light ON

not sure what cause this and what to do ?

also is this normal thing ?

Thanks

This is caused when the plastic casing is a bit seperated from the inner case due to the heat

the glue or seal that keeps the cases together parts away when the headlights are exposed to lot of heat i.e the sun

i can suggest a simple DIY job to fix this. I had the same problem with a signal light

It is not normal. You may have a leaky headlight cover. What's ur vehicle?

suzuki swift 2011 - I think this is manufacturers fault because the car is brand new and never touch headlight for any repair

If I may add to this- I replaced one headlamp assembly on my father's CE106V with an aftermarket lamp assembly and I noticed condensation on the inside of the lens after driving in the night. I think the heat generated from the bulb condensates on the lens as it cools. What can I do to correct this? I noticed that there are certain areas where the lens meets the plastic housing that are not sealed adequately. I was thinking of running some silicone along the edges.

Before applying silicon, you have to clean the inside. Better you go to delkanda area and get it done. Not too much costly. I got my head lamp done for 2000 Rs.

Any specific place machang ? I need to get it done as well, and how long did they take for it?

try Advance C** Au*** at Dehiwala. They did a good job for my KDH headlights. But costly. Rs. 4000 each. Delkanda chaps couldn't correct it.

For those who it may concern.

u can do it DIY.

Things you are going to need

* A Leaf blower or a hair dryer
* A Hot Glue Gun or a silicon glue gun

Step 1.
First Remove the Connections for the bulbs and remove the headlight

Step 2.
Remove the bulbs

Step 3.
Face the Blower of the hair dryer or the leaf blower and dry the inside for few minutes (if its a hair dryer switch it off for few seconds interval)
Or another alternative is to keep it in the sun for an hour or two

Step 4.
Slowly Apply the Hot Glue or the Silicon on the joint of the two cover and the case

Step 5.
Let the glue dry for a while. (approx. 30 mins)

and it will be done.
Worked for me. Ive done the same for a headlight of a Nissan B14 and a signal light of my current car and it worked both times.

sadly forgot to take pics when i did for the headlight.

Awesome, Schiffer! Did you completely separate the lens from the housing or did you work with a small gap?

[Schiffer]

worked with a small gap machan. didnt want to remove the whole thing

actually just hold the light and gently blow into the joint of the cover and case. there are some points where its not visilble to the eye but air rushes in.

even after applying gum and letting it dry double check for any air leaks.

If it is just couple of years old car then it can very well be a manufacturing defect unless it is the result of a minor accident. Assuming you get this problem occur only on one side (highly unlikely for both lights to show the same defect at the same time!) just check if the air vent at the back of the lamp enclosure is intact. You can compare between the two lights. If the leak is along the edge of the lens then it is a bit of a hassle to remove the lens and re-seal best done by an expert.

I did the same thing on a 10 year old Vitz headlight a couple of months back but in that case I removed the lens completely. The car was driven through recent torrential downpours but nothing happened so far. Good thing was that the original sealant was soft like chewing gum so I could easily pry the lens out. After doing all the cleaning and polishing I used a general purpose silicone tube to fill the grove and fixed the lens back. The important thing to note was the gap between the lens and the enclosure that had to be filled with silicone with the right amount of glue. You need the patience and dexterity of a pastry chef putting icing on a wedding cake to fill the grove in one go. If you stop in the middle and begin again you get unsightly silicone blobs here and there. You do not get a second chance when you fix the lens back in. If you do a mistake you will have to begin from square A. However, I do not think I have the courage to try it myself or even to advise someone to do it on a 2 year old car which is the subject of this thread!

Thanks man! I'll be trying it out tomorrow or on Saturday. This aftermarket unit looks great but it'll start to yellow after a couple of months no doubt!
