How to Identify the Production Date on Car Glass?

[DiTheo]

Method to identify the production date on car glass: Check the lower left corner of the glass, which consists of a combination of graphics, numbers, and English letters, including the car brand, glass brand, certification mark, glass type, and production date. The numbers represent the year, and there are two rows of dots to the right of the numbers. The first row of dots represents the month, and the second row consists of dots of two different shapes. It is normal for the markings on the front and rear windshields to differ, as they are different types of glass, and the manufacturer's part numbers also vary. Generally, the glass markings are a combination of graphics, numbers, and English letters, printed in the lower left corner of the glass.
