To paraphrase the Almond Joy commercial, sometimes you feel like a tint, sometimes you don't. In states like California, having any tint on your front windows is verboten. It's only casually enforced, but it's still illegal. In that case, something like this setup might come in handy: a Russian gent on installed two power windows in one door, and tinted one of them.
We don't know how much alteration was required to make the setup work on this car (it appears to be a Lada/VAZ model); one commenter asked if the door's support ribs had to be removed in order to fit the duplicate systems. Check it out for yourself in the video after the jump.
