How to Identify Vehicle Production Date from Window Glass?

[Steph]

On the lower left or right corner of the vehicle's window glass, there is a coded plate. On the last row of this plate, you will find a number and black dots, which indicate the production date of the glass. Here are the details: 1. The number represents the production year, specifically the last digit of the year. If the black dots are before the number, it means the glass was produced in the first half of the year; if the dots are after the number, it was produced in the second half. 2. Sometimes, owners may notice inconsistencies in the production dates of the glass on their vehicles, such as different dates for the front and rear windshields. This is because parts are prepared in advance during vehicle assembly, but there's no guarantee they will be installed immediately. Having glass with different production dates on the same vehicle is normal, so minor discrepancies in timing are acceptable as long as the dates are not too far apart.
