Dectane fogging issue
After patiently waiting for ten days I got my lights from Orange Tunning. Love them, worth every penny. After washing the car I noticed that there appears to be condensation inside the light, its foggy, hazy and it has been that way for a week now. Anyone had this problem? What can I do to fix it?

Don't know about the photo, but if I wash my car while the engine is still warm I get some condensation forming in the light. It goes away though by either driving or just letting the car cool down.
The lights are not sealed so they should be able to breath.

I got my DRL's from ROTech and rear LED's from XRteam on EBay. The driver side light filled up with water so I had to return and got new ones. There should be NO fogging or any moisture in any of the lights regardless of car wash or rain. The lights should be a sealed unit and if there is water getting in....something is wrong with the seal.
fvd's response to condensation....
Explanation of condensation in lights:
A frequently disputed issue is fogged glasses inside the lights. This
effect occurs after driving in rain or cold nights, and is a normal physical process. Through the light vents the expanding heated air gets discharged from the lamp housing. After the light is switched of, the light slowly cools down and moist air penetrates from the outside in through the vents. This moisture evaporates in the hot light housing and reflected upon cooling down as the condensation in the headlights. This process is called condensation. After a short ride in dry weather or after the light is switched on the evaporation process begins and the condensation dry of. Technically this process is safe because the reflector is protected against the effects of condensation.
A 100% sealing those lights would cause the following problem:
With just a little penetration of air (air has natural water content) and decreasing temperature water vapor would stick down at the coolest spot in the light housing. This moisture would go out very slowly or not at all.
Therefore, most systems are designed to be open so the moisture evaporates quickly.

I know some cars have small tubes in each lamp housing that drain and " suck " the air out to prevent moisture from settling. I saw that on a Volvo some time ago. I am sure others are sealed ( Audi A6 is sealed and when it leaks.. it cost you 600 dollars for a new unit)... Do not know about Porsches approach

Porsche's rear and front light housings are not sealed. They have rubber vent tubings for aerations, at least on mine.

Had the same problem removed the caps and put the oem rubber hoses and so far so good no issues .

I had some fogging issues right away and then I took the lights off, removed the 2 white plastic caps & blue fabric, and installed the oem tubes.
Important note, putting the tubes on is not fun!!
I heated mine up and tried to fit them on a dozen times. I eventually got them on but like I said... not fun.

Look closer! the clear caps and fabric covering inside the caps. Take those off. I never did transfer the hose from original taillights to my Dectane LED. It was too tough!
