So, you want them to look just like all the others and not be unique?
Why would it be different than has been published in numerous places?

How did he get the DRL LED's to flash like that at the end of the video? Anyone seen that before?
You will actually see that a lot with digital pics/video of LED lights. It has to do with the fact that the digital camera produces video by scanning the frame (I think it is called rolling shutter) and that produces some interesting artifacts. With LED I believe that it has to due with the LEDs being turned on/off at a high frequency. You can also see the effect if you take pics or video of spinning object like propellers where the bladed look all twisted.

It looks cool but LED's stay on unless they have a strobe function which would cycle them on and off at frequencies you mention. Let's see if anyone has seen this in person?
:screwy: We have seen the same thing in other video of LED taillights. It is an issue in the way it was recorded. The lights on the car are not doing this.

If you take any LED flashlight or headlight, turn it on and make a video of it it will not flash unless it has a strobe function. I am an early adopter of LED's and have countless LED lights. None strobe in video unless they have a strobe function. Do it yourself and you will see. LED's are usually constant on. When you watch TV and there's a night scene with cars, some will have LED's and none flash. Imagine if they did?

I'm not trying to be argumentative but I have seen LED's "flash" but it's because they have the function built in specifically which is called strobe. LED's would never advance in usage if every time you made a video using one you'd get flashing.
I can't speak for other leds, but the ones used in cars do cause this effect often. This is because LEDs flash at a rate imperceptible to the human eye, but recordings done in fractions of a second do catch it. When you see video, like a car commercial, where they do not, it's because they've used computers to simulate the correct lighting. This is pretty common knowledge.

This is a more technical explanation, if you require more explanation.

This was the most concise and perfect answer:
The LEDs flicker because you can't just turn down the power to dim them. They are connected to a PWM controller that turns them off and on quickly to produce the correct average light intensity for the situation.
This also helps with heat build up which is what kills an LED. Derating the light by reducing it's duty cycle will greatly increase it's useful life.

Thank u for explaining that further
