The function of the lighting of a vehicle is to see and be seen by other users of the road.
Between sunset and sunrise or in adverse conditions (Night, rain, fog, etc.) or tunnels:
a) Urban roads and cross-town roads:
b) On interurban roads:
It is mandatory to replace high beams with dipped/low beam headlights if there is glare.

A road is considered insufficiently lit when: you cannot read a registration (UK) / license (USA) plate from 10 metres or cannot make out a dark vehicle from 50 metres.
