IIHS Vice President and Chief Research Officer David Zuby noted that this alarming discovery warrants concern, particularly for those people who spend the better portion of their time behind the wheel in the dark.
“If you’re having trouble seeing behind the wheel at night, it could very well be your headlights and not your eyes that are to blame,” Zuby explained.
Researchers at IIHS put the tested vehicles’ headlights through a battery of tests, analyzing glare, distinctions between low and high beams, the types of lights used (like LED lamps or halogen) and their curvature. They also examined how the lights responded when driving from different angles.
The Toyota Prius v was the lone high performer.
“The Prius v’s LED low beams should give a driver traveling straight at 70 mph enough time to identify an obstacle on the right side of the road, where the light is best, and brake to a stop,” said Matthew Brumbelow, IIHS senior research engineer. “In contrast, someone with the halogen lights would need to drive 20 mph slower in order to avoid a crash.”
