Over the past few years the automobile industry has seen major advancements in headlight technology. Halogen bulbs are slowly being phased out for brighter, whiter high-intensity discharge (HID) or LED units. Brighter does not always mean better. According to IIHS, in a recent study of 31 midsize vehicles, only one received a good rating in the company’s first ever headlight ratings. The Toyota Prius V was the top rated car in the test when equipped with the LED lights, which are only available on the top trim. Pair the same Prius with the standard halogen lights and the rating plummets to poor. While these new headlight types have shown some advantages, the rigorous testing that included multiple approach angles, highlighted that many of the lamps produced poor illumination and excessive glare to oncoming traffic.
