It is always hilarious when the camera frame rate can catch the pulse rate of LED lighting, making the flashing apparent.

High-power LEDs aren't actually constant-on... they are flashed on and of at a very high frequency to try and drive the diode to emit as much light as possible.

When one frame of the footage has some LEDs on, and others off, and the next frame, different LEDs are on, and ones that were on, are then off... it goes to show how strictly binary the LEDs are... they have no warm up, or residual output after power is off...

But the rate of flash is so high, the eye and the brain interpolate them as being constant-on.

Yup - you've got it. Pulse-width modulation. http://en.wikipedia.org/wiki/Pulse-wid…

Yep. I actually love it. Especially in Top Gear's Ferrari 458 review. For some reason, the shot of the back end flickering while the confetti falls looks so cool to me.

The exception being Cadillac LED taillights which flicker at a rate that makes me see double when moving my head or eyes. Also makes me feel a little nauseous when I get stuck behind one of them.
