Retrofit auto lights function –

Anyone retrofitted the auto lights function?

I have adaptive bi-xenons and DRL lights (which turns on automatically with the ignition), but when it gets dark I have to turn the knob over manually (as well as when I stop the car I get annoyed by the beeping), and even more annoying, I have to turn it on and off in every tunnel around if I want to see the speed I'm going at, which can be quite annoying here in Norway with tunnels all over the place.
Is it just a question of replacing the light switch, adding a light sensor somewhere and do some coding, or is it more complicated?
