Rob,

Have you driven in an Audi 200 with Euro lights?  The light doesn't just
die 200 feet in front of the car.  There is a nice broad light that
stretches
into the distance.  The cutoff is such that the light shines below the eye
level of oncoming cars. There is also about a 30 degree rise to the right,
so that street signs may be easily read. On high beams, the effect is
more pronounced, with the light stretching 1/4 mile or more ahead.

On US DOT sealed beam lights, where there is no sharply defined cutoff,
the light fans out like a funnel. That is what blinds oncoming drivers.

HTH,
Kent
