Along with the LED technology more and more mature, there are a lot of car’s headlight assembly add the LED Optical system, like the compellent LED Tagfahrlicht Pflicht of Europe.

Driving with lights on during day (DRL)

In some countries like Scandinavia it has been a rule for many years and now is every-day-life to drive with lights on even during day. What thereby is most important is not "to see well" but "to be seen well". There are many arguments that strongly support driving during day with lights on:

Daytime Running Light can contribute to

reduce the number of accidents as other road users are seen earlier even in bad weather and traffic conditions
realize following road users earlier in the rear mirror and being able to adapt the own braking reactions according to minimize rear-end collisions
pedestrians and cyclists better realizing approaching vehicles
intensify reduced contrasts of the background that would hinder the view, like with clouds, sun reflexes, in areas with forests or trees.

There are studies that estimate the potential of rescuing human lives from a percentage of about 3 to 5 of the yearly serious car accidents.

To keep fuel consumption and CO2 emission on a relatively low level, there are special daytime running lamps, for example ini BMW 3series Cabrio/Coupé or Audi A4. Both headlamps clearly point out the opportunity to create an extraordinary styling with new technologies.

About OEM LED Headlights Headlamps

In rear lamps, applications with red and yellow LEDs already are state of the art in lighting technology. In headlamps, especially white LEDs are necessary that for main functions must provide a better light performance. White LEDs have already been used for signal functions like position or daytime running light in some serial projects.

With the development of the first Full-LED headlamp for Audi R8, Automotive Lighting set up a world premiere. For the first time, all light functions of a serial headlamp are being realized in LED technology, these are low and high beam, daytime running light, turn indicator and position light.
LED technology offers new opportunities for the future concerning styling, technology and energy consumption.
