Whose tail lights blink? I've seen videos of the tail lights blinking at a stop and going down the road. Mine don't do this. Feel me in on this. I've searched for the answer and came up with nothing. Maybe included in a certain trim package or all and mine aren't working? Thanks in advance.

LED tail lights are modulated to control brightness since an LED with constant voltage shine at one brightness. The modulation, turning them on and off rapidly, allows them to shine at the desired brightness. The higher the frequency the brighter they appear. This is usually between 100 and 200 Hz depending on whether it's running light or brake light. Since most video cameras capture images at 24 frames/sec it captures some frames where the lights are off hence the apparent flicker.

I bought an accessory for my '98 Pace Car that made my 3rd light blink. It was adjustable too! (speed and frequency). Cost me about 25 bucks back in 2002. I think they still sell them.
Stingray Chevrolet in Plant City, Florida installs them for free on every Corvette they sell.... That's what their website and salesperson told me.

its a video frame thing, I think, they don't really blink..DOT does not allow mfrs to blink lights....
Blink would indicate a visually perceptible effect which I agree, would not be allowed. They are in fact modulated which for 99.99% of the population is undetectable. Some, however, can perceive the flicker, usually in their peripheral vision. I am one of those if the frequency is below 200 Hz. Early implementations from 5 or 6 years ago are sometimes visible to me, most new implementations aren't.
