Why does Nissan put paint dots of various colors on the outside and inside of the windshield in the lower left hand corner? I have them on my 03 350Z, 02 Altima, and my dad has them on his 03 Altima. The colored dots on my Z are red, blue, and white. Red being the biggest. They are located right near the inspection sticker (NJ) location. Not very big, but looks as if they are there to intentionally denote or mark something. Just curious ?????
