HC Deb 10 March 1954 vol 524 c2237
48. Mr. Russell

asked the Minister of Transport and Civil Aviation if, in the next edition of the Highway Code, he will discourage the practice of some drivers of flashing headlights on and off before overtaking, as it is disconcerting to the driver being overtaken and dazzling to traffic travelling in the opposite direction.

Mr. Lennox-Boyd

I think this would be wrong. The Committee on Road Safety has advised that, provided headlights are properly aimed, this practice is useful and assists road safety.
