My new Tacoma TRD came with dark tint from the factory just as did the previous Tundra and my wife's Jeep. Most cars sold in the sun belt are equipped wirth dark glass. The front windshiled and front side glass are lighter tinted. We have this huge glowing orb in the sky that tends to parch us into dried up lizards---don't beleive me, move to Phoenix were we lived for a while---holy cow--sunburn in a car!!!
I would wish for Allan to get an inside sticker. I would prefer the outside type so I can put it on tanks, bumpers, my boat etc but anything is better than nothing.
