So the A5 has white LED's and the S5 has blue LED's in the headlights?

No, it is more about the blue light wavelength...
...and how it acts with respect to the entire light spectrum, and as a result, blue produces the most glare to oncoming drivers and illuminate the surroundings more poorly to the driver who has the blue lights.
Don't want to get too scientific here...but as you may remember from science class, Blue and violet are the shortest wavelength/highest frequency colors of visible light. Problem is, because they are they scatter the most readily. That is why when you see blue lights at night they always seem fuzzy and not crisp; the eyes have a hard time dealing with and focusing on the blue.
They are pretty much universally banned, not just in the US where our police and state troopers use blue emergency lights almost exclusively, but in other countries where the police may use other colors.
[As a side note, this is also why the sky is blue rather than any other color from the sun's white light output spectrum.]

Whoa, Check out the big brain on CNVRTfromBMW !
You a smart muthafvckr, thats right.
On many occasisons I have actually tried to explain to people that Xenons project white light that is very close to daylight and not blue or purple. The reason they seem blue sometimes is the curvature of the lens creates a prism effect and shows some color at certain angles.

It is more complex, but that is just remnant knowledge from "Jeopardy" study...
...for tryouts; but I chickened out before trying to actually get on the show! Why keep studying when I could be spending my time driving!!
