To ask His Majesty's Government what consideration they have given to creating new regulations on car headlight glare, in the light of the number of drivers reporting problems with dazzling, particularly from LEDs.

Regulations are already in place to help prevent headlamps, including those using LED technology, from causing dazzle and glare. Vehicle manufacturers must supply evidence that their new vehicles comply with international road vehicle approval regulations and the requirements applied to headlamps define maximum and minimum intensity, light pattern and position on the vehicle. In addition, domestic legislation prohibits the use of headlamps that cause undue dazzle or discomfort for other road users and headlamp aim is checked at the annual MOT test.

Police recorded collision statistics in Great Britain do not show any discernible trend over time that would suggest an underlying road safety issue linked to advances in lighting technology. The Department’s officials continue to support international activity reviewing the relevant vehicle lighting standards.
