This report is written primarily for automotive lighting and DA experts who were not present at VISION 2010 or who may have missed important lectures there. In 97 pages, we precise and analyse the main presentations.

This year, VISION's lectures, posters, night-drive demonstrations and booths combined to make an exceptional congress on new technologies with emphasis on the unprecedented speed and preoliferation of new and newly-mature technologies and techniques. More than 250 people attended.
The lectures cover:
- LED technology and its continuing improvements in optics, thermics, architecture, and power savings.
- Adaptive light systems, new technologies moving very fast with the arrival of cameras to implement intelligent automatic beam selection with the several corresponding adaptive systems, high beam assistant, horizontal and vertical adaptive cut-offs, glare free high beam.
- Technologies combining LED and adaptive light including LED arrays to produce AFS, matrix-beam systems, and spot marking light functions.
- Xenon technology and its constant progress; the great potential of new 25w Xenon systems to improve safety and reduce power consumption in comparison to Halogen
- Environmental aspects, within which the concept of the ?wattage index? shows that for average cars and speeds, good and safe Xenon/LED lighting can be provided that generates only 1g CO2/km saving more than 2g CO2/km vs halogen.

We were impressed by the charismatic presentations of Michael Hamm and Rainer Neumann, the fantastic slides and video of Michael Kleinkes, Thomas Manth and Stephan Berlitz and the technical lectures of Olivier Barthomeuf, Y.Kasai, B.Reiss, Steffan Sollner, and Georg Schneider, amongst others.

In the second part of the report, we present the drive night tests, with the main strong points:
- Performance differential with Xenon or LED is such that driving at night in bad weather conditions with legal halogen headlamps can legitimately be considered dangerous. Augmented, high-feature halogen lights with motorway and static bending functions improve the safety, but these complements are not enough.
- Xenon headlamps make night driving safe even in bad weather.
- LED headlamps have evolved significantly since the 2008 demonstration, and can produce a good light which permits safe driving at night in bad weather, with now equal Xenon performance in terms of beam flux and coverage.
- Automatic beam selection is at long last a dependable, high-performance feature which permits maximum possible use of the high beam.
The authors close the report with pictures of the VISION 2010 lighting community gathering and exchanging ideas about automotive lighting.
