A special subcommittee of the Automobile Club of China has been engaged for some time experimenting with dazzling electric headlights, such as are used on many motor cars in Shanghai, with a view to overcoming the blinding effect upon other users of the road, while providing effective lighting of the road for the driver of the car.
The report of the subcommittee is as follows:—
After conducting several experiments with powerful electric headlights, it was found that the best means of dimming these lights with to pedestrians, mot w to lessening
to paint on the outer glass of the headlight a black circle so as partly to obscure the glare from the bulb, and on a headlight of diameter of 9}in. a black circle of tin. seemed to be sufficient.
From tests made it was found that headlights with these black circles painted on them gave sufficient light to enable a driver to see his way clearly on the darkest of roads, and further, it was found that in driving acor and approaching a car which was equipped with this dimming 6 soon as one got there was no glare at all, and no dazzling effect to the eyes.
No experiments were carried out with acetylene headlights, but it is to be presumed that the same method would be applicable.
The Automobile Club requests members to deal with their headlights in accordance with the suggestions made and also to endeavour to induce those who are not members to adopt such measures.
