Why do LED headlights flicker when being viewed through a camera or recorded video but not when you look at them with a naked eye?
In: Technology
Because that’s how LEDs control their brightness. They only work at a certain voltage, if you want a dim LED you can’t just turn down the voltage. Turning it down beyond a very small window of where the LEDs will work will just cause the LED to turn off. LED’s brightness is controlled by turning it on and off very quickly, faster than the eye can see.
