saw a rainbow just to prove that you bought is really a polarizer, your windshield may itself with a polarizing film, do not look at the car with single polarizing glasses is good. You have not bought glasses, not good or the glass is not good, is a normal phenomenon, my car is Audi is the original glass’ have the same problem. If you don’t feel comfortable can be bought without polarizing glasses to drive
