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 developed 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.
