You may wind-up being one of those people who will only buy cars that are 10 years old, or older. According to CR, by 2019, 86% of the cars that they tested had LED headlights.
Here is some other info, courtesy of CR:
LEDs are more common than HID headlights, in much the same way that LED lights for the home have bypassed traditional CFLs (compact fluorescent lamps), and they’re popping up even in mainstream cars, SUVs, and trucks. We recently tested two affordable cars that came with standard LED headlights: the 2019 Mazda3 and the 2020 Toyota Corolla. The prices for each start under $25,000.
Why the swing? There are several factors at work.
Headlight styling helps win over consumers, says Steffen Pietzonka, head of marketing at Hella, a headlight manufacturer. “The different looking headlights and design are attractive to the buyer because the headlights are the eyes of the car,” he told CR.
In addition, LEDs are supposed to last far longer than the other two types of lights, which is a convenience and potential money saver for owners who plan to hold onto their car for the long haul. Last, LED bulbs use less energy than both halogen and HID lights, they run cooler, and they’re less of a drain on the vehicle’s electrical system. Ron Kiino, communications manager at Subaru, says that means there’s the potential to save money on gas as well.
According to Hella’s Pietzonka, “HIDs may be out of the market quite soon, because there are lower-cost options.” He adds that “in Europe, every new [car] development project in the industry has no HID/Xenon systems in the pipeline. In the U.S. it will be similar, with HIDs out in the midterm.”
