Cars: Lighting
The question
To ask the Secretary of State for Transport, if she will make it her policy to introduce measures to limit the brightness of LED car headlights.
Answered by Lilian Greenwood
All headlamps are designed and tested to international standards to ensure they are bright enough to light the road ahead but not so bright as to dazzle other road users. The standards define the beam pattern and maximum and minimum light intensities.
However, noting increased public concern, Government has commissioned independent research to better understand the root causes of headlamp glare and develop potential countermeasures. The work is underway and is due to deliver in summer 2025. Government will consider carefully the outcome of that research to determine what action might be appropriate.
