A couple of years ago I did an experiment with a pupil. I got him to drive on a quiet unlit country road on dipped beam at 30mph, select an object at the furthest point of his vision, and try to stop before he reached it. This was possible at 30mph, but when he tried it at 40mph, he couldn't stop before the object. The bulbs fitted to the car were the manufacturers standard halogen bulbs. This highlighted the point that you must observe as much of the scene as possible whilst on full beam, and use full beam when ever possible, even if only for a couple of seconds whilst holding the dip switch against the spring for a quick release.
