I wish that the B8 had LED tail-lights. When compared to the headlights the taillights look generic

LEDs light up much quicker giving the person behind you more time more time to react.
instead of rear-ending you. It's a safety thing. The fact that they also look better is icing on the cake.

Still paced by the reaction time of the person. That extra micro second doesn't buy you much.
Plus those things irritate the **** out of me when I'm behind a car that has them blasting all their red brightness into my retinas.

You're correct, but...
.001 seconds isn't going to make a big difference for the guy / gal in the overweight SUV whose talking on their cell, drinking coffee, and picking their nose while slamming into the back of you.

Its much more than ".001". More like .166
This was jacked from the internet. I can't believe that someone would defend incandescent bulbs vs LEDs.
"Standard incandescent brake lamps have a relatively slow rise time. It takes approximately a quarter of a second for them to reach 90% of asymptotic light output, causing potential delays in responses by following drivers. The present study evaluated reaction times to brake signals from standard incandescent brake lamps and from three alternative brake lamps with substantially faster rise times: neon, LED, and fast incandescent. The study, performed in a laboratory, simulated a daytime driving condition. The subject's task was to respond as quickly as possible to the onset of either of two brake lamps in the visual periphery, while engaged in a central tracking task. Brake signals were presented at two levels of luminous intensity. The results showed that reaction times to the alternative brake lamps were faster than to the standard incandescent lamp, with the advantage averaging 166 ms for the LED and neon lamps, and 135 ms for the fast incandescent lamp. A reduction of the signals' luminous intensity from 42 cd to 5 cd increased the reaction time by 84 ms."

Yeah it does. I cannot beleive that someone would defend incandecent bulbs over LEDs
They also:
1) Last the lifetime of the car
2) Use much less energy
Whatever floats your boat I guess. But for some reason I believe that if the A4 had LED tail-lights that you wouldn't have a problem with it. Would you?
