How to Read the Production Date of Automotive Glass

[KadenLee]

Method for checking the production date of automotive glass: There is a code at the bottom left or right corner of the car window glass. The last or second last row contains a number and several small black dots indicating the production date of the glass. The number represents the production year of the glass, and the small black dots represent the production month. Below are detailed explanations: 1. Meaning of the number: The number indicates the production year of the glass, representing the last digit of the year. For example, if the glass shows the number 8, and the vehicle's manufacturing date is in 2007 or 2008, then the glass with the number 8 was likely produced in 2008. 2. Meaning of the small black dots: The small black dots indicate the production month of the glass. If the dots are in front of the number, subtract the number of dots from 7; if the dots are behind the number, subtract the number of dots from 13. The result will be the production month of the glass.
