How to Identify the Production Year of Car Glass?

[VioletLee]

The production year is usually clearly marked on the glass, represented by numbers. Detailed information is as follows: 1. For example, if the glass was produced in 2014, the number '14' will be displayed on the glass. There will be a series of small black dots either before or after this number, which indicate the production month of the glass. 2. If the small black dots are in front of the number, subtract the number of dots from 7 to get the production month. If the dots are after the number, subtract the number of dots from 13 to determine the production month. 3. The production date of the glass should be earlier than the production date of the car. Knowing how to read the glass production date can help determine if the glass has been replaced. 4. If the glass production date is later than the car's production date, it indicates that the glass has been replaced. The car's production date is usually found on the vehicle's nameplate located on the B-pillar.
