The blue tint disrupts your sleep cycle and helps keep you awake when driving at night. There's definitely a trade off to be had depending on where these lights are located though.

Red is also really low contrast, at least at non-night-vision destroying lumen levels.

It's not really the "blue" part. It's the "forcing yourself to be awake when you shouldn't be" part that disrupts your sleep cycle. Driving at night when you should be in bed is so much more the problem than whatever color the light is. For you as human at least =)

That's the point -- the blue is to help break the cycle further and keep you awake, when your body insists otherwise!

says what evidence? it's pretty much been debunked for a long time, and the whole premise is apparently based on bad science. I'm pretty sure i read an article here on hn that showed that this whole blue light scare was based on old science with extremely limited sample sizes and extreme exposure. i tried to link to an article from 2016 that still says that it affects sleep because i hastily read the first part. trying to dig up the article i read seems to be hard, but at least I'm still pretty sure that the science is not settled on the matter at all.

Do you always link to articles supporting your opponents view? (Hint: read the last section of the article)
