 Quite frankly anything StVZO is like my exposure light likely to be
overkill in terms of cost.

About the cost: For a long time I got by fine with various lights that were very inexpensive. I experimented a bit with many headlights and lighting arrangements, including rechargeables and home brews. I mostly used dynamo halogen lamps by Union and Soubitez that focused the beam quite well and were adequate for all my road riding, but not really outstanding. The only setup that I considered a significant improvement was two halogen lamps powered by my dynamo, and switchable (A or B or A+B).
But when I got my first B&M Cyo, I considered the problem solved and stopped experimenting. It's a little pricey (~$100?) but I've spent far more on other bike equipment. I can afford it, and it's such an improvement. For me, it gives a luxurious amount of illumination.
