Electric Lighting

New indirectly reflected lights sharpen the outline of pedestrians on residential streets as well as main traffic arteries in Greensburg, Pa., reported by the Westinghouse Electric & Manufacturing Company lighting engineers to be the best lighted city of its size in the United States.

The new lights apply the theory that objects are seen best at night by contrast. The roadway surface is bathed in light for several blocks into the distance.
