flickering headlights

I have a question. Several videos (and I've seen then all ) for the new F80/82 have shots of the headlights flickering and think it looked awesome. How do they do that? Is it when the flashers come up? A special add on?

It is just an inadvertent effect of the filming. The lights cycle at a rate that you can't see with your eyes. When a car is filmed the frame rate of the film and the cycles of the lights are not in sync so the camera is actually catching the light when it is off.

Bummer! I was hoping to do the "flash" at will. Looks so cool.

I'm sure if you start yanking on some wiring in the engine bay you can get some flickering lights going... let us know how it pans out!

Yeah try taking a video of a tube TV/monitor (if you can find one) or even a picture of your laptop monitor - you'll see the scan lines. It's caused by the scan rates of the video camera sampling the scan rate of [electronic light], in this case the LEDs
