Super head lights, sure you can see like it day light outside, but oncoming traffic is blinded. I wouldn't consider that too safe if oncoming traffic blinded by halogen lights.
I can remember my old 53 ford with generator and 6 volt system on narrow dark street, now those were the days of not being able to see. Now we got train lights shinning in or eyes, only thing missing is the sway back and forth.
IMO the brighter the light in old eyes the less you can see.
