Thanks - it was definitely hard to visualize with only the (oddly) un-illustrated article. Without going all the way to version "E", I've noticed that a setup not pictured, with two full-sized headlights side-by-side in the normal just-under-the-handlebars location (round or rectangular didn't matter) instantly made it far easier to identify the motorcycle and judge distances. The single headlight just looks too much like a car with one dead headlight (especially since standard riding technique is to not ride in the center of the lane), and it takes seconds to figure out if I'm looking at a bike or a car possibly halfway into my lane. Two headlights it's instant, and also upgrades it to a 2D object in a black field, making 3D judgements much easier, as the spacing between them widens on approach, etc.. I think the best setup would be a dual-headlight setup in the illustrated "E" setup.
