My wife seems to have a lower persistence of vision than most of us; the LED taillights drive her crazy. I can see them in my peripheral vision, or when I'm very tired.

Cadillacs seem to be the worst for blinking to me.

Yes, I have noticed the Cadillac's as well.

I read an article about light perception of the "eye-brain" connection several years ago, and it went on to say that quickly blinking lights are perceived more quickly by the brain than solid lights.

They actually did studies to determine that a on/off frequency of around 100 to 200 Hz makes this effect more noticeable.

I have no idea what frequency the Cadillac lights are run at, but they certainly grab your attention.

The article did not mention it, but I suppose one could get an energy savings by reducing the duty-cycle of the lights while pulsing them.
