no thats why windows, back glass, and windshields are made out of tempered glass. i assume lights are made out of a thinner glass and im sure they are not tempered. but i might be wrong

windshields are NOT tempered glass... they are LAMINATED safety glass.... all the OTHER glass in the truck/car (with a few exceptions...) is tempered.
