§ 40. Captain Pilkingtonasked the Minister of Transport and Civil Aviation what experiments he has made in the use of amber-coloured headlights for motor cars, such as are required in France; and his conclusions.
§ Mr. Boyd-CarpenterTests carried out by the Road Research Laboratory showed that there is little difference between white and yellow headlamps of the same intensity in seeing distance or degree of dazzle.
§ Captain PilkingtonHas my right hon. Friend been in touch with the authorities in France on this matter, and can he say whether they consider the use of amber lights satisfactory?
§ Mr. Boyd-CarpenterWe have investigated French experience, and I think that the impression which my hon. and gallant Friend has that French headlights dazzle less is due to the fact that, on the whole, they are of a lower power rather than of a different colour.
