All the studies I've found seem to say something along the lines of "blue light disturbs sleep", which seems like exactly the needed effect if you're driving at night.

You're thinking of 'promoting wakefullness' like a cup of coffee that has an immediate effect that wears off when it leaves your system.

'Disturbing sleep' means they alter your hormone production & release, which is something that begins to affect you over weeks and months.

High color temperature lights disturb sleep- without promoting wakefullnes.

The light has an effect during the night as it blocks the melatonin hormone from kicking in. It takes about an hour of darkness for the hormone kick in and make you sleepy. On very long occasional drives it's probably safer to trade some sleep disturbance for a more wakeful drive. If it's your daily commute it'll probably mess up your sleep.

And if it's on your residential block, it'll definitely mess with your sleep.

Yeah, screw that. I wear some cheap blue blockers before bed. I look like Bono but it works :)

Yeah, until you drive out of the highly lit area. Then your eyes will have to take some time to adjust to the low light.
