HC Deb 15 February 1966 vol 724 cc234-6W
Mr. Ron Lewis

asked the Minister of Transport what representations have been made to her by the Road Research Laboratory for the compulsory introduction of a dimmed headlight system; and what reply she has made.

Mr. Swingler

None. We have arranged for the Road Research Laboratory to conduct a controlled experiment using the dim/dip headlamp system on a number of G.P.O. vehicles and we are grateful to my right hon. Friend the Postmaster-General for his help. The aim of the experiment is to find out whether use of the dim/dip system reduces accidents. Until the results are available the system must be regarded as experimental but there is no objection to any driver using it.
