That means never having to change an incandescent or gas-discharge lamp again, from the headlamps to the dipped beams, since LED light sources have a useful life of approximately 10,000 hours – a vehicle's entire service life. They also consume very little energy and are therefore fit for the times: A production LED headlamp in the new S-Class, for instance, reduces energy consumption by a whopping 72% compared with a conventional halogen lamp. To put it another way: it saves 2.1 grammes of C02 per kilometre. Moreover, LED technology is significantly easier on the driver's eyes: their colour temperature of 5500 K is very close to daylight, compared with alternative halogen or xenon lamps .
And the headlamps adapt automatically to suit the weather, lighting and driving conditions, thus further improving driving comfort and ensuring optimal visibility in any situation.
