Better night vision is largely thought to be to increase the amount of light. One needs to be able to see through the darkness into a lighted area. Looking through light rays into a lighted area does not increase the vision all that much. As long as the actual light is not projected upwards, and stays level or slightly downward you will be in good shape. This is part of the reason they went away from the rounded head lamps and use the flat front style with built in projectors. From your last photo there is a lot of light projecting upwards.
Looks that way but if you see my garage light its distorted as well, my camera phone just freaks out I guess and cannot focus. I understand what you are saying about the light beams and have my two center lights 1.25 feet off the ground at 25 feet away, my fogs are 4" at 25 feet away. Recommended for my center beams is 1.5 feet off the ground at 25 feet away so I put them just a tad lower.
I have tested them at night and its a night and day difference, this is something I should have done a long time ago.
Oh btw I think with my photo its because I had everything on including my high beams, trust me when I say I can see really well. Photos sometimes do no justice.
