Is it normal for the production dates of the front and rear glass of a new car to be different?

It is normal for the production dates of the front and rear glass of a new car to be different, as long as the production date of the glass is earlier than the manufacturing date of the entire vehicle. Car glass is uniformly purchased by the manufacturer from suppliers and is procured in advance for vehicle assembly. Due to different procurement batches, the dates will naturally vary. Unused glass from the same batch may be installed on the next vehicle. Method to check the production date of car glass: Look for the trademark in the corner of the car glass, which consists of several dots and a number. The number represents the production year of the glass. If the dots are on the left, it indicates the first half of the year, while dots on the right represent the second half of the year.
