How to Check the Production Date of a Car Windshield?

[LeJake]

There is a code located at the bottom left or right corner 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. The number represents the year. The black dots represent the production month. Below is relevant information about the glass production date: 1. Production date of the glass: The number represents the year. The black dots on the left or right of the number represent the production month. If the black dots are on the left, they represent the first half of the year, and the number of dots is subtracted from 7. If the black dots are on the right, they represent the second half of the year, and the number of dots is subtracted from 13. 2. Example: .....4: The number 4 represents the year 2014, and 7-5=2, meaning the car glass was produced in February 2014. 4.....: The number 4 represents the year 2014, and 13-5=8, meaning the car glass was produced in August 2014.
