asked the Secretary of State for Transport what guidance and advertising has been issued by his Department on the introduction and proper use of dim-dip lighting.
None at present. I shall keep the matter under review and issue appropriate guidance if necessary. As the system does not demand any change in people's driving habits—they can use their sidelamps, automatically enhanced by dim-dip when the engine is running, or their headlamps as they choose in dull weather, twilight or in lit streets. Headlamps remain a legal obligation at night on an unlit road or in seriously reduced visibility.
