The whole point of a warning light is to be noticed - I certainly don't regard mine as an issue because my vision is focussed way down the road, not a few cm in front of me.

You can get stickers to go over it - like a sort of smoky film.

The 'full beam on' whatsit in my car is orange so I don't notice it - recent research has shown that there are certain photoreceptors in our eyes which strongly respond to blue light; tests on humans have shown that, when sat in an environment with blue lights, the area is perceived as being 'brighter' than other colours.

Ahhh, that may be slightly misleading; we need all of the wavelengths and a lot of animals see into the IR range. We have several kinds of photoreceptor pigment on our retinas - there's one called rhodopsin which helps us see in the dark and one called melanopsin which is specifically sensitive to short wavelength light (blue will be 410-500nm ish).

Get scoffing the riboflavin!

It is

The blue mainbeam light on my two cars are bright too, but I've come to welcome it as a reminder, since although both cars are the same make, they have different dipswitches - one is single-action (pull switch towards and let go for changing beam either way), the other is two-position - main and dip. So it's not totally impossible for even a very attentive and careful driver such as my good self to get dipping wrong without a reminder!!
