There are two main categories, which we do have to cover from legislation point of view 1) Harmonization of legislation with all kind of light sources (Halogen, Xenon, LED) and all kind of light applications standard dipped/main beam, AFS, LED-array generated or micro-mirror variation of light distributions 2) Driver assistant lighting systems with external parameter variation of light pattern (e.g. Adaptive Driving Beam, Predictive AFS, Car to Car Communication) G T B The International Automotive Lighting GTB Document No. CE‐4563 23 and Light Signalling Expert Group Groupe de

hurdle for automatic levelling and cleaning device was historically introduced to avoid glare caused by high power Halogen bulbs (HIR bulbs) 2. There is and was no scientific argument for a 2000 lm definition and limit for whatever automotive Front-Lighting request 3. This has caused some confusion and coresponding special solutions
