A growing number of drivers in the US are complaining that modern car headlights are excessively bright, causing glare, disorientation and- in some cases- posing a hazard on the road. The issue has gained traction, with widespread mentions across social media, podcasts, and online forums. The experience of being dazzled by SUVs, trucks, and electric vehicles seems to be increasingly common.
According to experts, there are two main reasons behind this phenomenon:
- The widespread adoption of LED headlights, which emit a cooler, bluish light that appears more intense to the human eye
- A genuine increase in headlight brightness over the past two decades, driven by the pursuit of better visibility and higher safety ratings in crash tests
However, this technological progress has its downsides: increased risk to pedestrians and cyclists- especially at night- and a rise in traffic-related fatalities involving distracted driving, a figure that has increased by 48% since 2014.
Organisations such as the Soft Lights Foundation are calling on the federal government to set limits for headlight brightness, particularly on the blue light spectrum, which tends to cause the most glare. Currently, there are no official regulations in the US setting maximum brightness levels, or requiring headlight alignment checks after vehicle maintenance.
At the same time, some car manufacturers are incorporating advanced systems like adaptive beams and automated headlight adjustment. These features are still limited to higher-end, expensive models, however.
Overall, modern demands for safety inside vehicles may be creating new safety issues outside them- and the solution may ultimately lie not in technology alone, but in political will and public pressure.
