How to Check the Date of Car Glass?

[StAnna]

There is a code in the lower left or lower right corner of the car window glass. The last or second last row has a number and several small black dots indicating the production date of the car glass. The number represents the production year of the glass, and the small black dots represent the production month. Here are the details: 1. The number is the production year of the glass, representing the last digit of the year. For example, if the glass has the number 8, and the vehicle's production date is in 2007 or 2008, then the glass with the number 8 was likely produced in 2008. 2. The small black dots indicate the production month of the glass. If the black dots are in front of the number, subtract the number of dots from 7; if the black dots are behind the number, subtract the number of dots from 13. The result is the production month of the glass.
