This is a great idea. I have an addition to it tho. Polarize diagonally - for descriptive purposes, forward slash (/) and back slash (\). Now orient the polarization of all headlights as / from inside the car (\ facing the front of the car) and a polarizing filter on all windshields in the same orientation. Then oncoming headlights will be completely dimmed but yours will not.
This was suggested decades ago. The main problem is the filters on the headlights dim the light by almost 50%. The brightness could be upped in some way.
Worse is the driver so equipped with either polarizing filter on the windshield or sunglasses has all the light from all lights other than his own headlights reduced by a similar amount. There is no way around this part!
Oohhhh i see, sorry about the fake thing, guess i should of asked my question first lol... well i bought some oakley half jackets and i got them polarized so wat does this mean
Don't you know how polarizers work? The headlights of my truck have a polarizing filter covering them oriented in one direction, I'm manipulating another polarizing filter in front of the camera. When the two polarizing filters are oriented parallel to each other the light passes through. When the two polarizing filters are oriented perpendicular to each other the light dims. The light on the building does not have a polarizing filter therefore there is no effect.
I had this idea recently, independently of any external inspiration. It's a wonder why this isn't standard on all cars, but then again the car companies initially resisted seat belts.
The only problem with this is that you have to put polarizing filters on the lights of other cars, so it won't work until it is standardized. In the meantime, you could try a filter on the windshield and some polarized glasses, although that might reduce too much light from outside.
You need two polarizing filters. One on the headlights one on the camera. When they're 'parallel' you see the light...when they're 'perpendicular' it cancels the light out.

Can a polarizing filter reduce light streaks caused by a CCD sensor?
