LED headlights have gradually become a commonplace addition to new-vehicle models, taking over for halogen headlights. But this transition is more than just a technological evolution. It has had benefits for the way drivers are driving during and after business hours in low-light level situations. Improvements include better illumination and beam focus. Improved illumination is the most apparent difference from halogen lights. LED headlights can illuminate dark roadways 25% farther than their halogen counterparts, and high-beam settings on LEDs offer a significant improvement over low-beam settings, according to a study from AAA. How an LED headlight projects the beam illustrates how it is an improvement over halogen headlights, according to Greg Brannon, director of automotive engineering and industry relations for AAA.
