Electric Lighting

November 25, 1962

A new road lighting system in which the illumination would be provided by auxiliary lights carried on automobiles for the benefit of approaching cars has been devised and tested at Indiana University by Dr. Merrill J. Allen, professor of optometry.

The above photographs show how the system works. In the left-hand photo, without the auxiliary lights turned on, three men standing in the road are nearly invisible. In the right-hand picture, they are easily seen with the lights turned on. In the I.U. tests, sealed beam lamps are carried on the front bumper and directed to the sides and backward. They are turned on automatically when the car’s lights are dimmed.
