I note "shine out at a different angle" in Phillip's
original message:  Someone experiencing Euro-pattern lights
for the first time might be "surprised" by the deliberate
rise-to-the-right designed into these units to provide
better side-of-the road illumination.  (How many hyphens can
I get in one sentence?)

http://lighting.mbz.org/  provides the most comprehensive
discussion of headighting I've ever seen, and beam patterns
are thoroughly discussed in the FAQ.  (Yes, this is a
subsite of the Benz club!)
