     expressed in percentages, which is allowed to pass through a surface
     to the amount of light falling on the surface.

     glass-coating material or who fabricates, laminates, or tempers a

     reduce light transmission through the windshield; or
  (2) Which has material and glazing applied or affixed to the rear
     windshield or the side or door windows, which material and glazing
     when so applied or affixed reduce light transmission through the
     windshield or window to less than 32 percent, plus or minus 3 percent,
     or increase light reflectance to more than 20 percent.

(c) The provisions of subsection (b) of this Code section shall not
    apply to:

    the Department of Motor Vehicle Safety.

(e) No person shall install any material upon the windshields or
    windows of any motor vehicle, the installation of which would result
