(The new side indicator lights are HUD blue with white letters with very evenly back lit white EL sheeting.)
Instead of fabric the vents openings are replaced by black Plexiglas with recessed openings for each side status indicator. A smoked piece of Plexiglas goes underneath that so that the 'vents' appear all black until you turn the car on and then the side indicator lights show.
