Each year, approximately 5,000 pedestrians and bicyclists are killed along U.S. roads – 2,300 of them occurring at night – and another 70,000 pedestrians are injured in traffic crashes, according to a 2003 National Highway Traffic Safety Administration report.
New automotive lighting technologies, including Xenon and Adaptive Front Lighting Systems, can help improve nighttime pedestrian safety, according to the Motor Vehicle Lighting Council.
According to researcher Michael Flannagan of the University of Michigan Transportation Research Institute, drivers “overdrive” the headlights on many of today’s vehicles, meaning they are going too fast to stop safely within the distance made visible by the headlights.
“The critical safety need in low-beam lighting is seeing distance,” Flannagan said. “The maximum safe speed with today’s average low beams is only about 45 mph. Our studies indicate there is a major safety problem that headlights could address.”
One possible solution is Xenon headlights, also known as High Intensity Discharge or HID. Based on a gas discharge process, Xenon uses an arc...
