Woah that is awesome.

Sequencing tail lights were on offer for some vehicles back in 1966.

I built one back in the 80's using a 555 and 4017.

The latest one I helped repair fitted into the lamp socket, and had a chip on it that detected the number of pulses and turned the LEDs on based on that.

Each one was designed to be in a certain position within the 3 tail lights, and at all times one or more lamps were on.

They also fitted an electronic flasher since the LED tailights didn't present enough load to flash correctly.

There are a few circuits around for them, but as Samuel has pointed out, they may not be legal, so check first.

The ones on the Audi can be done using neopixels and there is some code here.

Wireless Challenge .... the other bit -2

Wireless Challenge .... Beer Tap (the other bit) - 4  Assembly

Whether they end up legal may be the issue due to various laws regarding angles, brightness, etc.

Can anyone help to create something like this.

I have seen the circuit you are talking about I think thy call them knight rider circuits.

The code to drive the neopixels is there in the post.

The best way to learn is try yourself, you'll be amazed with how easy it can be by breaking it down into smaller chunks.

Get hold of some neopixels from a supplier that has documentation and support (that excludes some of the asian suppliers).

Try their demos and examples to get it working, then try modifying them to do different things.

This builds your knowledge of using them. (for instance mine wouldn't do what I wanted but I discovered I was starting at 1 instead of zero)

Then progress until you build what you want, and configure it as you want.

If you want these instantly, then I suggest buying the Audi in the video.

Sorry I have too many other projects to build these.
