I can’t prove it, but I suspect that a lot of people are suffering from having backlit phone, console, and cluster LCD panels in their face while driving. The dim incandescent glow of the speedometer as the only thing illuminating the cabin is a thing of the past. This makes me think that folks actually need more lumens on the road in front of you because your pupils are not at all dilated for the dark.

Meanwhile the color temperature and spectra of LEDs vs halogen lights could not be more different. I honestly think our eyeballs respond to to these things differently and it just so happened that halogen is/was easier on our eyes in a lot of cases.

BTW, I’m not excusing anyone for blinding other drivers where it can be helped, especially manufacturers. That shit drives me up the wall.
