How to Check the Date on Car Glass?

[VanManuel]

Look for a series of symbols and numbers in the lower left corner of the glass. Below is an introduction on how to read the production date of the glass: 1. How to read: On the bottom line, there are several small dots followed by a number. Taking "…4" as an example, the number 4 represents the year. If the black dots are before the 4, it indicates production in the first half of the year. The calculation formula is "7 - number of black dots". For example, 7-3=4, so the glass was likely produced in April 2004. If the black dots are after the 4, it indicates production in the second half of the year, and the calculation formula is "13 - number of black dots". For example, "4…" means the glass was produced in October (13-3=10). 2. Main function: By checking the production year on the windshield, you can roughly estimate when the car was manufactured, as the car's production date is generally later than the glass production date. 3. Additional function: Comparing the production dates of the glass can clearly indicate whether the windshield has been replaced. This has a significant impact on the evaluation of used cars.
