When driving at night, what is the safest approach for a driver to adopt?

Drive with full headlights on at all times.
Drive at the maximum speed limit with full headlights on to see clearly ahead.
Drive at the maximum speed limit with dipped headlights on at all times.
Drive at a speed that enables the driver to stop within the distance ahead that they can see to be clear.

Explantion: When driving at night in good driving conditions the dipped headlights of a car will typically let you see 30 metres ahead. So, you should travel at a speed that allows you to stop in that distance.
