HC Deb 16 December 1959 vol 615 c170W
63. Dr. D. Johnson

asked the Minister of Transport if he will make regulations to compel the use of cadmium yellow headlamp bulbs in all motor vehicles, with a view to prevention of dazzle.

Mr. Marples

No. There is no evidence to suggest that yellow headlamps giving the same seeing distance as white lamps cause less dazzle.
