I hope it doesn't engage at night, as we don't have turquoise LEDs so the blue ones will ruin night vision.
The idea of preserving night vision is based on rod cells being insensitive to light with a wavelength >640nm (ie red). Halogen bulbs found in headlights produce a lot of light under that wavelength, and are going to be at a much higher intensity than turquoise indicator lights.
Tangential, but holy shit, this is great to know, and explains why I generally feel blinded every time someone with those horrible headlights drives by.
I wonder if there’s anything that can be done (to my windshield? to some glasses?) that can reduce the impact of this at night?
