Sketch, what film did you use? I got mine from 3dlens.com (
http://www.3dlens.com/shop/polarizer.php the last one) and ended up getting it to work, but it didn't turn out very nice. The part that is supposed to be black is a dark red (I have a red LED) and the number is a light red, plus if I look at it at the wrong angle, like the driver seat or passenger seat (not head on)

, I can't see anything at all. I tried putting more than one layer of film on each side of the lens, but that didn't work either
