What is the appropriate light transmittance of motorcycle film?

The light transmittance of motorcycle film depends mainly on the location of vehicle use and personal needs. For the front windshield, the light transmittance is recommended to be between 70% and 78%, because the light transmittance in this range can provide a good view while avoiding glare and glare when driving. If the owner has poor eyesight, it is best to choose a film with a light transmittance of more than 73%. For the side windshield and rear windshield, according to the national standard "Technical Conditions for Motor Vehicle Operation Safety", the light transmittance should reach 50%, while the light transmittance of the front windshield and the side window used by the driver to observe the exterior rearview mirror when driving should reach 70%.
In actual selection, the owner should determine the light transmittance of the film according to the light transmittance of the vehicle's own glass. If the original vehicle glass has a higher light transmittance, such as 80%, then the light transmittance of the selected film should be higher to ensure that the overall light transmittance meets or exceeds the legal requirement of 70%. In addition, there are films with higher light transmittance on the market, such as up to 90% light transmittance, which can not only provide a clear view, but also effectively block ultraviolet rays and heat.
When choosing a car film, in addition to considering the transmittance, you should also consider other functions of the car film, such as heat insulation and UV blocking, to meet your personal needs. At the same time, make sure that the transmittance of the selected car film meets national safety standards to ensure driving safety.
