How much do you know about auto glass?

Automotive glass has always played the role of "shielding from wind and rain" in our cars, but how much information do you know about the information it carries when it leaves the factory? For some car owners who intend to buy second-hand cars, you need to know more to avoid being "fooled".

The picture shows a piece of Focus rear windshield. There is a set of trademark codes in the lower right corner. This is mandatory by national regulations. All car glass must have it. They are usually located on the lower left or lower right of the glass. on the bottom corner. Among them:

1. FORD...is an OEM product specially produced for Ford

The black dot is in front of "8", indicating production in the first half of the year. The calculation formula is "7-number of black dots". For example, the car glass in the attached picture is .8, which should be 7-1=6, so this piece of glass should be 2008 It was produced in June of the year; if the black dot is after "8", it means it was produced in the second half of the year. The calculation formula is "13-number of black dots", such as "8..", which means the car glass is 13-2=11, It was produced in November.
