1. Ever heard of high beams? Could those possible be useful for seeing people and animals?
2. The cygolite and night rider lights i use have focused optics. It's incredibly dishonest to claim otherwise.
3. I see zero interest in stvzo guidelines for manufacturers outside of continental europe.
4. Stvzo standards when it comes to light throw and flashing are designed for the convenience of motorists, not the safety of cyclists.
These beam pics illustrate how the aggressive shaping of the philips beam reduces spread at a distance (and forms an inverted cone):
