I posted this on the C7 forum as well.

The last edition of Automobile magazine had an interview with Cesar Muntada, Chief of Lighting and Wheel Design for Audi. I would certainly like the full Matrix/laser technology, as used in the EU, but, as stated, the technology has still not been authorized for use in the USA even though Audi has petitioned for it.
The other issue that was not even mentioned is that Audi have gone through hoops to put on a light show at the rear of, at least the A7 and A8, but still hasn't incorporated the travelling amber turn signals. His team of engineers were given the task of taking a great design, that is used in the rest of the world, and screwing it up for the US market. It's not that difficult to accommodate the antiquated US laws of initial illuminated area for a turn signal, especially if you have a team of engineers specifically designing lighting systems. If they really are that incompetent then at least launch a petition to change that law too.
There are numerous people within Audiworld from different forums that have spent thousands of dollars on rear lights so that they can get amber turn signals and be a safer member of the motoring public. So, why does Audi supply its US market with this antiquated, inferior product?
My next car will have amber turn signals but I am not paying extra for them.

Having red turn signals is a dumb idea. Red for brake, red for the light and red for the turn signal. It makes as much sense as having red, red and red on traffic signals instead of the red, amber and green. Only in the North American continent can such stupidity be tolerated.

Arent the rear turn signal lights on the 2019 A6 Prestige Trim amber color? I thought only the Premium Plus and lower that have the red rear turn signals.
And by the way, where is your CD/DVD player you listed on your 2019 A6 Prestige?

I do not know of any new Audi sold in the USA that has amber rear turn signals. We need Doug to answer your Prestige question.

Nevermind. Just verified my own question — . See video at 8:56. The US version only has the red DRL rear turn signals.

Incredible isn’t it?

I am not sure of the difference between the two lighting systems of the premium and prestige but neither of them have the matrix enabled in the USA.
The amber lighting laws have been discussed extensively on numerous forums but here’s the summary: Amber is legal. Surface area of the illuminated area of the turn signal must be a defined size - the initial area of the traveling system does not meet this requirement so Audi illuminated additional lights as well. A really cheap and dirty method of meeting dumb legal requirements and having the semi traveling feature. This biggest issue is that all Audi’s don’t utilize amber even though it is legal.
