Because the car light is tight, it is easy to cause water when it is cleaned and rained, but when the temperature difference between the inside and outside is bigger, the fog will be produced.
建议：遇到这种情况，比较好不要进行高温烘烤。因为，车灯的材料一般都是塑质的，如果烘烤温度太高，会导致车灯外表软化变形，影响使用和美观。
Suggestion: in this case, it is best not to bake at high temperature. Because the material of the lamp is generally plastic, if the baking temperature is too high, it will result in the softening and deformation of the car lamp, which affects the use and beauty.
另外，现在的车灯一般都是整体式的，透明的灯罩后，还粘有一个保护灯体的背板，温度太高会导致粘合胶质熔化，增大车灯进水的可能。
In addition, nowadays the headlights are usually monolithic. After the transparent lampshade, there is a backboard with a protective lamp body. The high temperature will lead to the melting of adhesive colloid and increase the possibility of water intake.
一般来说，车灯内的水分在白天阳光照射下很快就能蒸发了。
In general, the water in the light of a car will soon evaporate under the daytime sunlight.
However, if your headlights often have water, it is better to check the body of the lamp to see if it is caused by the crash and the frequent inflow of the lights.
