The Audi R8 was setting standards as early as
2008 as the first sports car with all-LED head-
lights. Now this special lighting is also available
for the Audi A7 Sportback on request. All-LED head-
lights not only require less energy than standard
lighting systems, but also provide a brighter
light which is perceived to be much more pleasant.
The dipped beam consists of a distinctive line of
three individual light modules. This makes the
Audi A7 Sportback unmistakable, even at night.
The main beam
, daytime running lights and
indicators are also made in LED technology. The
use of the same material for all functions makes
completely new lighting effects possible. The new
Audi A7 Sportback, therefore, has the right light
for every situation: It has a motorway light
which, at speeds above 110 km/h, automatically
almost doubles the range of the light cone (from
approx. 70 m at dipped beam to 120 m with mo-
torway light). In addition, the A7 Sportback has a
combined daytime
running light/indicator light
unit and an all-weather light which makes con-
ventional fog lights superfluous.
The individual
LED modules are skilfully controlled to redistrib-
ute the light, reducing glare from rain or fog.
LED headlights
Less energy, more light:
the Audi A7 Sportback with all-LED headlights.

Subject: Light
Conventional light bulbs reach temperatures of up to 300 °C. Due to their sophisti-
cated technology, LED lights are somewhat more sensitive and should not get hotter
than 150 °C. Because of the engine, the temperature of the area around the head-
lights is already around 120 °C. In theory, then, LED headlights would need an addi-
tional cooling system to be able to work. However, the Audi engineers did not want to
spoil the good low-energy credentials of the LED headlights, so they quickly devel-
oped something completely new: a fan which directs heat away from the LED chips.
The special feature of this fan is its additional benefit. The high operating tempera-
ture of standard bulbs means that they can defrost the headlights, which LEDs can-
not. The newly developed fan directs warm air from the LED chips directly to the
headlight lens and thus defrosts them and prevents them from misting up.
