Light-emitting diodes (LEDs) have a whole series of technical advantages over conventional bulbs, the most important being their activation speed and their long service life. If a trailing driver can notice the brake lights of the leading car sooner, that driver’s reaction time can be quickened, potentially resulting in a shorter stopping distance and/or avoiding an accident. LEDs can last an entire vehicle lifetime, consume up to 50 percent less energy and take up less space. Selected Audi models use LEDs for rear light functions (tail lights, brake lights, turn signal indicators), in the side turn indicators, and in daytime driving lights.
