I like to see where I'm not headed yet, too, as when I go down my steep driveway and need to be able to see to make the curve to the left onto my bridge and over my creek. All I use on my helmet is a little Blackburn Flea, USB-rechargable, but it really helps. The stupid helmet does more for (or against) my neck muscles than that little light. I don't aim it at other people.
I don't encounter other bicyclists at night, so I'm always kind of bewildered by your focus on bicyclist's lights blinding on-coming traffic. Maybe in Europe they enforce automobile headlight rules, but not around here. The cars headlights nearly all blind me, and I can't see where my lights are a problem, in comparison. That guy's web site you shared with us mentions something like what I deal with:
"
Outside cities, where you will encounter unlit paths, roads on which cyclists may ride which lay parallel to a road for cars and the worst problem is cycle paths lying below the road for cars: You need a lot of light and
none of the commercially available dynamo lamps are good enough in all those situations. The last is most problematic: You need a lamp like the Philips LBL to see the road on low lying cycle paths (because you get the low beam of cars shining in your face). Serious cyclists who ride outside the city may want to ride fast (say 30 km/h, and much more with a tailwind), so the headlamp for outside-city use should have a good reach, ca. 50 m or more.
The only dynamo setup that is good enough for all these situations is my modified LBL + special dynamo driver, which is the first headlamp with which I could even properly see the road and what's beside it on the low lying road 3 where you get the low beam of cars shining downwards on you/in your eyes in which case an Edelux is in no way enough..."
At least I'm not trying to ride down in the ditch beside the road, I'm on the same level as the on-coming cars.
To be fair, Europe does have quite a high specific population density ... meaning houses are usually in estates and uninhabited land is protected. Indicating that people over here do encounter each other quite often ... and most of the cyclepaths are lit ... most XC ski paths in forest are lit as well
My point is that StVZO takes into account the higher probability of interaction with another motorist, cyclist or pedestrian.
