HEADLIGHT UNIFORMITY. Publication: The New York Times Date: 18 November 1917 Topic: Society of Automotive Engineers |
In an effort to obtain uniform State laws regulating automobile headlights, representatives from New York, New Jersey, Connecticut, Massachusetts, Rhode Island, New Hampshire, and Pennsylvania met with a committee from the Society of Automotive Engineers last week in the Engineers' building.
Many States have been approving certain makes of anti-glare devices, but these are only effective if the lamp is properly adjusted before the anti-glare device is fitted, which means that placing the stamp of approval on any device is useless.
The restrictions on any headlight to prevent glare require the beam of light not to be higher than 42 inches from the surface to the road. It was admitted that present legislation is not satisfactory, but no definite conclusion was reached as to the correct method of enforcing the 42-inch rule, which all agree is the desired condition to be had with lamps.
