Imagine you are driving in mountain with zig zag road and the next way of the road is turning to right , so the lights will turn to light the road and will give comfort to your driving because you don't discover to late the road.

This system should have been produced on a DS, but never made.

Oops, here I go breaking my promise not to discuss old cars in a general forum!

Citroën DS (most models of DS from 1967, as opposed to cheaper ID) did have road-following headlights. Take a look at this photo: inboard lights are high beams that follow the steering wheel. Here is a photo of a model without them (either ID or earlier model DS - I am not sure).

Another interesting relic from those glorious times, Citroën SM (M is for Maserati) - a coupe based on DS with Maserati engine - also had hydraulicaly operated road-following and self-leveling headlights (photo, details) - but not on the variant for American market. I also know this firsthand, because an acquaintance of mine has three SMs. (Interesting sidenote: several four-door variants of SM existed, including one convertible (SM Presidentielle) - of course, there were two-door convertibles, too.) For a good resource see, for example, here.
Searching the web for good photographs, I stumbled on several American shops specialising in Citroëns, one specifically in SM. I didn't see roadgoing 2CVs there, though .
