Yeah but more bright is more safe ... for me driving around with the light of a thousand suns coming out of the front of my care at night it seems pretty safe, "good luck everybody else".
Often less bright is safer. Unless there are heavy clouds the moon (even a partial mood) is often bright enough that once my eyes adjust (which takes time!) I can see better without any lights at all. When my headlights are on I see really good in the space where the lights are, but beyond that I see nothing, when my headlights are often I can't see as well in that area, but I see much farther. I want everything that can to have lights so they are easier to see, but I can see a candle from miles away so this is minimal. With no lights at all I have better chances of seeing things that don't have lights in time to take action.
