‘HID

(high-intensity-discharge) headlights enable drivers to see more

effectively at night than conventional tungsten-halogen lights… Based on field experiments in which drivers responded to objects in

their field of vision while using both sorts of lighting, LRC

researchers concluded that drivers using HIDs were better at

“detecting edge-of-roadway hazards, such as pedestrians and

animals… “[HIDs] produce more light, last longer, and use less energy,” … “There’s no question they result in better visual

performance. Now we’ve quantified that,”

HIDs are widely used on European automobiles and are growing

increasingly popular in the United States. The National Highway

Traffic Safety Administration has ruled HIDs do not exceed

maximum illumination standards.’
