Dear all,

 

Car is 6 month old and now in winter time I noticed mist in lights after I drive it.

It doesn't matter if I drive it 15 minutes or 2 hours, mist appears and it takes one full day of not driving a car to disappear.

 

Is this normal or should I contact dealer?

 

Thank you!

Remove the back cover and the bulb, then get a hair dryer in the hole to completely dry it out, then replace and see how it goes

 

Think there are a number of threads on this.  A recent example:

The short answer is, misting is normal. Water droplets are not. That’s when you go do the dealer.

Can you please describe how can i remove back cover?

I tried to remove back cover and can't find it under the hood and behind lights.

Can it be removed without extraction of light?

Misting is normal for LED lights as there isn't enough heat to dry out moisture. There shouldn't be water droplets unless the moisture has gathered into droplets. There is reference to this in the manual for cars with LED lights.

Basically remove the headlight  back cover as if you're  changing  a bulb stick the hair  dryer in the hole  for about 15 mins on high

Don't follow this advice!! A hairdryer on high in a confined space reaches a very high temperature! You will almost certainly damage the headlight internally, melting/distorting the plasic internals and internal moving parts and damage the LED unit, wiring and optics.

 

It will cost you several hundred pounds per side to replace LED headlights.

 

In any case it will not solve the problem because the units are ventilated, not sealed and outside air/humidity invariably gets drawn in and misting will happen when there is humidity and a temperature difference inside/outside the unit.

 

Its a design consequence and theres no easy fix.

 

Good luck with melting/distorting plastic with a hairdryer! Remind me what they make them from since forever?

 

I agree that it wont achieve anything regarding the headlight condensation problem.

If you take a hair dryer apart you will see the heater element is mounted inside a mica tube that shields and protects the plastic shell from the heat of the elements. If you restrict air flow , as you would in the suggested method above, the elements will glow red hot, and the air going into the lamp would easily get hot enough to damage silvering on plastics and much more. Please be my guest and try it on a Skoda plastic led headlight, they are only 600 euro each from Skoda-parts.com if you should damage it.

 

 

 

Most of the plastic welding that I have done in recent years has been Skoda headlights, I will give you a clue, I did not use a hairdryer

 

And I also know better than to buy anything especially headlights from Skodaparts.com, Superskoda etc!

 

I am relieved to have your retrospective permission to have repaired my accident damaged headlights.

 

The RH dipping Hella headlights (OE) that I bought had been shrink wrapped with a heat gun, they put out as much heat as the blowlamps that they replaced & would set your hair on fire if you used one as a hairdryer.

All I can say is if anyone is stupid enough to follow the advice of sticking a hairdryer on high setting inside their LED headlight and leaving it there for 15 mins to cook, and suffers any subsequent problems they can send the bill for replacements to J.R.

I’m not sure how using a hair dryer will work long term anyway. You’re heating the air, which then cools and will...well, condense on the lens.
