If you're talking about how the center of the lights are dimmer than the rest of the light, it's because the '10-'12 tail lights have reflectors inside them so that they are DOT/SAE certified. The reflectors don't let as much light through it but it's hard to notice that in person. A camera can pick up on the difference in brightness much better which is why it's so easy to see in the video.
