How to Install Axial Black Projector Headlights with Halo & Corner Lights (97-03 All) on your Ford F-150

"Because of this fact a condensation o» the inside of the lens may come ifwe have the contrast of humidity and high temperature from the inner housing and environment, specially in winter time or humid weather. "      

"Condensation can occur, for example, after driving through a car wash, steam cleaning the engine and the vehicle front, which changes in temperature overnight and similar situations." 

"Especially in the post heating, where the still hot engine heats the backside of the headlight and the same time the lens is cooled by the cold air outside you will have low moisture in the headlight on the lens" ​

Due to the open, but splash-proof ventilation system, which is necessa-ry to equalize the pressure, it comes within the headlamp to different „climate zones" and subsequently to the fogging of the lens. That oc-curs cool and warm areas in the headlight. The warming is effected by the heat emitted from the light source and the cooling of the lens by the airflow. Because of the maze-like air vents the heated and expan-ding air will be displaced from the headlight. Thereby humidify will be sucked into the headlight. 

Because of this fact a condensation on the inside of the fens may come if we have the contrast of humidity and high temperature from the inner housing and environment, specially in winter time or humid weather. 

Condensation can occur, for example, after driving through a car wash, steam cleaning the engine and the vehicle front, with changes in tem-perature overnight and similar situations. 

Especially in the „post-heating", where the still hot engine heats the backside of the headlight and the same time the lens is cooled by the cold air outside you will have a low moisture in the headlight on the lens. 

In lenses with clear glass, which can also be toned, is this phenomenon more visible than in lenses with a structure. 

This condensation in a significant part of the headlights lens must dis-appear after around 20 minutes with switched on low beam. Remai-ning surfaces of the lens can nad may be misted after that. 

The process of misting is =tired physically and doesn't influence the optical headlight function (light power) in any way The condensation also occures no corrosion in the headlight. 

Condensation phenomenon can be found in any lights, also in those from competitors, because it is a physical reason. Therefore a replacement for the item is not admissible, it is not a technical defect in regard to the warranty.
