Light-emitting diode (LED) lights are brighter, more energy-efficient and longer-lasting than traditional bulbs, making them a cost-effective choice for many state departments of transportation. However, how these lights affect animal behavior is not well understood.
To learn how insects, reptiles, amphibians, birds, mammals and other wildlife are affected by LED lighting, the California Department of Transportation initiated a research synthesis of published literature. With more than 300 relevant studies identified, the results offer a valuable compendium of resources highlighting the known or probable effects of LEDs on wildlife.
