Where is the manufacturing date of car glass located?

[WilliamMarie]

The manufacturing date of car glass is usually marked at the lower right corner of the window or below the trademark. Here are the specific details about car glass coding: 1. Date reading method: Numbers represent the year, small dots represent quarters (there are 4 quarters in a year, with a maximum of 4 small dots), and large dots represent the months within a quarter (a quarter consists of 3 months, with a maximum of 3 large dots). 2. 3C certification: The authenticity of the glass determines its shatter resistance and the extent of injury it may cause upon breaking. A qualified car glass product must have 3C certification, and this 3C certification mark should be clear and extremely difficult to scrape off with a blade.
