Annoying Headlights

Too ... much ... light!
Let me start this off by saying I know that it’s not most peoples fault that manufacturers are producing more powerful headlights. Today it’s all LED that or bi-xenon this, the downside is they’re too bright. Those who drive will know how annoying it is to have someone with ridiculously bright headlights behind you at night kinda hurts the ‘ol eyes. The downside is, of course, that the driver really can’t do much about it. The only thing I can think of is dipping the lights as you can change the dip with a control in the car. This however does reduce how much of the road gets lit up and so negates the wonderful powers of your fancy headlights.
So is there a way to cure this? In all honesty I have no idea, I’m not a car designer but there’s surely a way to get round this problem. Whether it’s toning down how bright they are or perhaps increasing the dip without reducing how much of the road gets lit up. I just feel that other drivers on the road can’t be ignored, I know you can flip the rear-view mirror to reduce the brightness but you can’t do this on wing-mirrors or your wind-shield for those that come the other way. In my own personal view this is the second worst light based annoyance on the road. The worst are those people who refuse to turn off full-beam or turn them on even though you’re still “within range” when following you. In the end though this can only be fixed by the manufacturers themselves and well it’s unlikely to change. Still if you do drive and use full-beam please, for everyone’s sake, don’t switch back on until you’re sure you can’t see the car in front at all!
