HC Deb 01 December 1982 vol 33 cc197-8W
39. Mr. Neil Thorne

asked the Secretary of State for Transport what evidence he has received of the benefit to road safety which could be obtained by making vehicles more conspicuous at night in urban areas.

Mrs. Chalker

It is generally recognised that moving vehicles using only side lights are difficult to see. There is also evidence that dazzle from modern headlights even when dipped, reduces the conspicuity of other vehicles and road users. There will therefore be benefits to road safety from fitting vehicles with dim-dip devices so as to make them more conspicuous at night in urban areas without the risk of dazzle.
