70 LED headlights
The Audi R8 was setting standards as early as
2008 as the first sports car with all-LED
headlights. Now this special lighting is also
available for the Audi A6 and S6 on request. Full-
LED headlights 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 nine individual light modules. This makes
the Audi A6 and S6 unmistakeable, even at night.
The high beam, daytime running lights and
indicators also feature LED technology. The use of
the same material for all functions makes
completely new lighting effects possible. This
gives the Audi A6 and S6 the right light for every
situation: they have 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 motorway
light). In addition, your vehicle has a combined
daytime running light/indicator light unit as well
as an all-weather light which makes conventional
front fog lights superfluous. The individual LED
modules are skilfully controlled to redistribute
the light, reducing glare from rain or fog.

Conventional light bulbs reach temperatures of up to 300° C. Due to their
sophisticated 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 headlights is already around 120° C. In theory, then, LED headlights
would need an additional 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 developed 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 temperature of standard bulbs means that they can
defrost the headlights, which LEDs cannot. 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.
