Understanding Material Degradation and How to Prevent It
Many low-cost Car Door Lights on the market use plastic projection panels, commonly known as films.
While plastic materials are lightweight and inexpensive, they are not heat-resistant and can degrade under long-term exposure to sunlight or continuous illumination.
Over time, this leads to a loss of transparency — the panel turns hazy, cloudy, or whitish, a process known as material fogging.
This fogging is not caused by moisture, but by thermal and environmental stress that affects the surface of the plastic.
As the material degrades, the projected pattern becomes blurry, faded, and less vibrant, eventually requiring frequent replacement.
Three Main Causes of Car Door Lights Fogging
1. Heat-Induced Degradation
Plastic panels cannot withstand high temperatures. When the light operates for long periods or the vehicle is parked under the sun, the panel’s surface gradually deteriorates and becomes hazy.
2. Loss of Optical Clarity
As fogging increases, the projection pattern loses its sharpness and color saturation, resulting in poor display quality.
3. Reduced Service Life
Material aging shortens the product lifespan, forcing users to replace the panels more often — increasing both cost and maintenance effort.
