LED Headlights Can Be Brighter but Often Lack Clear Advantages

Automakers have embraced light emitting diodes (LEDs) in headlights, and their use is becoming more widespread. At Consumer Reports, 55 percent of the 2018 models we tested had LED headlights. Of the 2019 models we've tested, 86 percent had LEDs. LEDs are small and can be used in a string of lights, giving car designers more leeway in how the headlights look. But in CR's testing, we discovered that these new lights don’t offer any more illumination than traditional halogen and/or high intensity discharge (HID) headlights.
