you live in ca ... you can tint the back windows dark as you want. I have 6% on back 3 of my accord and then nothing on the windshield or fronts .... it looks real nice and it really isnt that hard to see out of at night ... what do you need to look out the back for anyway ... for backing up get some hyperwhites in your reverse bulbs so it will be birhgt and youre set. Id think this entire forum drove dx's the way people bitch about having to roll down the window.
