I believe that many consumers will give away car stickers when they buy a car, just as they will give away corresponding mobile phone stickers when they buy a mobile phone. It is true that car stickers can block ultraviolet rays, prevent explosions, and protect the privacy of passengers. Then some novice car owners asked, is it better to use dark color film or light color film? After reading these points, I believe you will have the answer.

1、就阻挡紫外线、防晒而言

1. In terms of blocking ultraviolet rays and sunscreen

许多车主在贴膜的时候选择深色膜很大一部分原因是认为深色膜比浅色膜能更有用地阻挡紫外线，尤其是女车主到了夏天很怕太阳晒，就会默认深色膜。然而殊不知汽车贴膜的隔热效果是由隔热层决定的，而不是染色层。而市面上一些劣质的深色膜甚没有隔热层，更何谈阻挡紫外线。

Many car owners choose dark film when applying film. A large part of the reason is that they think that dark film can block ultraviolet rays more effectively than light film. Especially when female car owners are afraid of the sun in summer, they will default to dark film. However, the heat insulation effect of automobile film is determined by the heat insulation layer, not the dyeing layer. And some inferior dark films on the market even have no insulation layer, let alone blocking ultraviolet rays.

2、就性而言

2. In terms of safety

车主在选择前挡风玻璃贴膜的时候，建议不要使用能见度太低的膜，因为前方视线是车主大的视线来源，如果在前挡风玻璃贴上能见度低于百分之50的膜，会直接影响到车主的视线，严重的还会引发隐患，因此前后挡风玻璃建议贴浅色膜。

When choosing the film for the front windshield, it is recommended not to use the film with too low visibility, because the front line of sight is the main source of the car owner's line of sight. If the film with visibility less than 50% is pasted on the front windshield, it will directly affect the car owner's line of sight, and even cause serious safety hazards. Therefore, it is recommended to paste the light color film on the front and rear windshield.

3、就保护隐私而言

3. In terms of privacy

汽车就好比是车主的二个家，如果在保护隐私的方面而言，深色膜相对来说更占优势。一些深色膜具有单向性，即车内看得到车外的环境，但在车外的人却看不清车内的环境，这样一来有用保护了乘坐者的隐私，同时还可以防小偷窥视。

The car is like the owner's two homes, if in terms of privacy protection, dark film is relatively more dominant. Some dark films are unidirectional, that is, the environment outside the car can be seen inside the car, but people outside the car can't see the environment inside the car clearly. In this way, the privacy of passengers can be effectively protected, and the thief can also be prevented from peeping.

车主们在选择贴膜的时候不仅要考虑到实际需求和行车性，同时也要学会辨别真假膜，不要贪一时便宜，毕竟一些劣质膜实际上一点用处也没有，反而还会有隐患，切记不要得不偿失。

When choosing the film, car owners should not only consider the actual demand and driving safety, but also learn to distinguish the true film from the false one. Don't be greedy. After all, some inferior films are not useful at all. On the contrary, there are potential safety hazards. Remember not to lose more than gain.
