The determined mean beam patterns clearly show that today's headlamps exceed the basic requirements laid down in ECE regulations. Halogen headlamps provide good lighting performance and contribute positively to traffic safety. Xenon headlamps give an impact to higher illumination on the road while glare values remain on the same level. The increasing market share of xenon headlamps will also increase the overall lighting performance. It is to be expected that in a few years the rate of HID headlamps is as high, that they dominate the mean light distribution running on European streets. Additionally, the project has proofed that it is possible to design on the one hand the light distribution of halogen and xenon headlamps to higher performance than actually required without increasing the glare level on the other hand. This is demonstrated not only with single engineering samples but with a large variety of different headlamps and types of headlamps. Traffic safety with respect to lighting performance will be further increasing.
