Tinting is different.

26708 (c) Notwithstanding subdivision (a), transparent material may be installed, affixed, or applied to the topmost portion of the windshield if the following conditions apply:

(1) The bottom edge of the material is at least 29 inches above the undepressed driver's seat when measured from a point 5 inches in front of the bottom of the backrest with the driver's seat in its rearmost and lowermost position with the vehicle on a level surface.

(2) The material is not red or amber in color.

(3) There is no opaque lettering on the material and any other lettering does not affect primary colors or distort vision through the windshield.

Tinting has some measure of transparency, and therefore is allowed. But clearly, as defined, lettering or a vinyl strip are not allowed as they are not transparent.
