First of all, you can take a look at the picture below to explain in detail the meaning of each mark on the car glass.

In the picture above

“8”— -Represents the year 2008;

"..."——The three black dots to the left of 8 indicate that the month is the first half of the year. Subtract the number of black dots from 7 to get the specific month of April.

If the black dot is on the right side of the year, then subtract the number of black dots from 13, which means the production month is the second half of the year.

So, the production date of the glass in the picture above is: April 2008.
