What is the difference between 07 and 17-year car glass?
2 Answers
You can distinguish between 07 and 17-year glass by looking at the numbers on the glass. Here is the relevant information: The numbers represent the year: The production date of the car window glass is indicated by a combination of dots and a number. Regardless of the car glass specifications, there is a string of symbols in the lower left corner of the glass, with a corresponding number below the symbols indicating the production year. This number can be used to check the production date of the car window glass. The number represents the year of production. Black dots represent the month: Small black dots indicate the month of production. For example: "7", where 7 represents the year, indicating production in 2008. If the black dot is before the "7", it means production in the first half of the year; if the black dot is after the "7", it means production in the second half of the year. Explanation: The number is the last digit of the production year of the glass, representing the year. The specific production year of the car window glass can be determined based on the vehicle's manufacturing date. If the vehicle's manufacturing date is in 2007 or 2008, then the glass year number 8 would correspond to 2008. The glass and the vehicle's production date cannot differ by 10 years. Therefore, for glass from 2018, the glass year number would also be 8, but the vehicle's manufacturing date would be 2017 or 2018.
I've driven some older cars from around 2007, and the glass was truly outdated, mostly just standard laminated or tempered glass with poor UV protection. In the summer, the car would get as hot as a steamer, and the noise isolation was weak—you could hear the wind howling on the highway. Now, driving a 2017 model, the glass has been significantly upgraded. It includes infrared-reflective coatings, which greatly improve heat insulation without causing glare. Some even come with integrated heating wires and rain sensors, preventing ice buildup in winter and automatically activating the wipers, making long drives much more comfortable. Additionally, the 2017 glass is thinner and lighter, offering clearer visibility without interfering with signal reception, unlike older cars that frequently fogged up and required manual handling. If you often take long trips or drive with kids, these improvements are quite practical and enhance the daily driving experience, though they do come at a higher cost.
