So, people see best in the wavelength around 500nm which is a green/blue color. Why aren’t car headlights this color to improve visibility? Why can’t you buy headlight bulbs that emit bright green light? A white light with a green filter would just make it more dim, but on headlights you want brightness.

Thank you all for your answers. It totally makes sense that non-green objects would appear ‘unilluminated,’ if that’s a word.
I think my idea originated from night-vision goggles being green due to the…. phosphorous? Maybe? It’s been a while.
Maybe I need more experience in different narrow-wavelength lighted rooms.
Again, thank you all for your quick and perfect answers.
