Lighting
There are two types of crosswalk lights: those that illuminate the whole crosswalk area, and warning lights.
The Illuminating Engineering Society of North America currently provides engineering design standards for highway lighting. In the USA in conventional intersections, area lighting is typically provided by pole-mounted luminaires. These systems illuminate the crosswalk as well as surrounding areas, and do not always provide enough contrast between the pedestrian and his or her background.
There have been many efforts to create lighting scenarios that offer better nighttime illumination in crosswalks. Some innovative concepts include:

Famous quotes containing the word lighting:
“There is no more miserable human being than one in whom nothing is habitual but indecision, and for whom the lighting of every cigar, the drinking of every cup, the time of rising and going to bed every day, and the beginning of every bit of work, are subjects of express volitional deliberation.”
—William James (1842–1910)
“Popular art is normally decried as vulgar by the cultivated people of its time; then it loses favor with its original audience as a new generation grows up; then it begins to merge into the softer lighting of “quaint,” and cultivated people become interested in it, and finally it begins to take on the archaic dignity of the primitive.”
—Northrop Frye (b. 1912)
