Interesting Euro Spec Tail lights
 

On a business trip in Germany, saw a lot of A6's where the turn signal on the rear tail lights actually "swipes" towards the outer sides of the car. Have you ever seen this?

That is cool. A vagcom change?

I'm a fan of turn signals like that. Just something a little different. I know mustangs do that but not sure of anything else.

Have no idea on this one. These were A6's, and clearly the signals had a series of bulbs (or LED's, it was tough to tell). I don't know the bulb composition of our tail lights and whether this is even possible.

Another feature not allowed by the US DOT.

The tail lights on my car are tinted red, and there are no amber LEDs that I know of in the tail light. I design integrated tail lights for motorcycles so I have a ton of experience with LED tail lights.

There would have to be a clear lens portion where the turn signal LEDs are located. You can't put Amber LEDs behind a red filter (tint) as it would filter out most of the amber light.

For these reasons I'd say no way is it a VAG setting.

The European spec is yellow rear turn signals. I think this is possible with our US spec red lights. The signal will be red, but the sequential action is probably possible through VAGCOM.

This is not possible through VAG-com and is Euro spec only. It is completely illegal in the US due to DOT regulations.

Darn Hyper - you're no fun!

Seriously though, how come Mustangs can come with the sequential tail lights and DOT approved them?

DOT also requires front amber markers and a lot of us have disabled them via VAGCOM. Come to think of it, DOT requires a lot of things that people who like to mod disable or bypass.

Does anyone know if the Euro spec lights are built differently to the US spec other than using amber LED diodes instead of red?

Haha, I know, Im such a buzzkill.

However, Im happy you asked about the Mustang. It is the only vehicle that has been approved for the sequential lighting because it falls under the proper parameters. The main one being the first light(or LED)in the segment has to be the size of at least 6x6" square. Any subsequent light can be any size. Unfortunately, the LED segments in the Audi lights are all the same size around 1x1" square.

So there you have it.
