Oscillating Brake Lights

[MWS]

I was watching a video from the Fabspeed website of a 911 S that they have added several performance enhancements. I noticed that when they are driving the car and apply the brakes, the brake lights seem to oscillate on and off. Can anyone tell me how that is done?

The guy from fabspeed posted that it is an artifact from the DSLR he was using to video the car runs. Maybe he did not want to admit to an illegal mod to the brake lights, but that is what he told us!

DV is captured at a higher framerate (60fps typical) than most eyes can parse. Traditional movie film, for example, runs at 24fps and unless your eyesight is "quick" you don't notice a stutter. LEDs oscillate. Most of us see a constant stream of light from them, but a video camera captures their "flicker."

If you stare at some of the newer LED Christmas lights you might start to see what the video is capturing. They certainly play tricks on my eyes.

I hope that few make the mistake of installing flicker on their brake lights--sounds dangerous and silly to me, since a constant red is the internationally-standard "I'm braking" notification.

"...LEDs oscillate..."

"Flicker", NOT oscillate, and then only in a 120VAC 60 hz light "string", not on a 12VDC automotive power supply. Unless we're talking about "oscillate" in the aspect of the molecular level.

The ones available at superbrightleds.com FLASH (1-2 seconds..??) when the brakes are initially applied and then go solid RED.
