HC Deb 07 December 1966 vol 737 c315W
Sir Clive Bossom

asked the Minister of Transport what evidence she has that white headlights are better than yellow headlights in the interests of road safety.

Mr. Swingler

The Working Party set up to review the lighting regulations has recommended that the standardisation of headlamps can contribute to road safety and that they should show white light; there is no significant evidence that yellow is a better colour than white, which is far more widely used.
