Hi with these dark nights I have noticed that our new car Al's dipped headlights make driving on unlit roads stressful. I have tried raising the dipped aim with the dash controls but still there is complete darkness! Beyond the twenty yards or so lighted tarmac even cats eyes are not lit and it is not always possible to use main beam. I am thinking of going to the dealers and get them checked but it could be that the lenses are very good and do not leak any light beyond the legal limits, quite unlike a lot of cars with their dazzling high intensity lighting! (BMW) flooding the road for miles and blinding those of us coming the other way.
