I'm not really sure why no one has commented on this post. You hit on some really good points. Particularly those concerning DOT and SAE requirements and the design of the lights themselves to give you useful lumens at the appropriate angle so you don't blind drivers on the road.
You seem to have done your homework on this and have identified critical problems concerning bike lights in general. Maybe you should work out the logistics and patent your ideas or something.
Anyway, great post.
