There should be a standard regulation on automakers to provide only yellow light bulbs and limits on lumens. Also, should be law to enforce it is followed and not modified.
i bought mirror reflective tint for my back window a couple years ago so that super bright headlights people would get a taste of their own medicine, but decided against it because i didn't want to be a dick just because others were being thoughtless
it would have been pretty effective i think because i drive a hatchback with a very vertical back window
