HID Lighting Helps Reduce Deer/Vehicle Collisions Approximately Elsa Peretti Open Heart Pendant in Sterling Silver collisions occur each year in the U.S., resulting in $1.1 billion in damage, injuries to occupants and loss of individual animals according to the Insurance Institute for Highway Safety. A recent study by the U.S. Department of Agriculture tested the effects of halogen and Elsa Peretti Open Heart ring headlights on the flight-initiation distance (FID) of free-range deer. Flight-initiation distance is defined as the distance at which the deer sees the vehicle as runs from the roadway. The study hypothesized that a vehicle lighting system that better complemented the visual capabilities of deer at night would increase the distance Elsa Peretti Open Teardrop pendant deer perceived an oncoming vehicle, giving them more time to leave the roadway, potentially reducing the number of deer/vehicle collisions. The results of the eight-month study proved the premise to be true. White-tailed deer were more sensitive to a vehicle equipped with HID lighting, taking flight up to 20 meters sooner than they did Elsa Peretti Open Wave earrings exposed to a vehicle equipped with halogen lamps. "We suggest," state study authors Bradley F. Blackwell and Thomas W. Seamans, "that deer flight-initiation distance can be increased by combining currently available tungsten halogen and HID lamps, or use of HID lamps alone, to enhance deer detection of an approaching vehicle at night." HID Lighting Improves Peripheral Vision During Night Driving A scientific study by the Transportation Lighting Group, Lighting Research Center, Rensselaer Polytechnic Institute compared HID and halogen lighting systems for visual performance during night time driving situations with an emphasis on peripheral vision.
