I took some video of a Model S today at the Houston event, and in watching it when I got home, I realized something about how the lights work (headlights and tail lights, at least the borders). They are not just on or off--they constantly paint just like a TV screen.
1) Is this true of all cars with LEDs?
2) Is the purpose to save power?
I can post a video if I'm not making sense, but it is extremely clear from the video, perhaps because I used a cheap camera. I tried to Google to find the answer and got into pages that discussed beat frequency and Kell factor, but nothing in relationship with car headlights and tail lights.
