How to Check the Vehicle Production Date on the Car Glass?

[KylieMarie]

The production date of the glass can be checked using the following methods: 1. There is a code at the bottom left or right of the car window glass. The last or second-to-last row contains a number and several small black dots, which indicate the production date of the glass. 2. Some new cars may have inconsistent production dates for their glass. For example, the left rear and right rear windshield production months may differ. In reality, it is possible for glass production dates to vary during vehicle assembly. The vehicle assembly plant is just that—an assembly plant. Parts are stocked in advance and cannot always be assembled immediately, making it difficult to synchronize the timing. Additionally, different batches of glass naturally have different production dates. 3. Some glass may also have a few thick black dots following the production year and month. These dots are used to specify the week of the month.
