The government is reportedly planning to launch a review into vehicle headlight brightness following growing concerns from motorists about dazzling glare from modern LED lights.
Research into the issue on behalf of the Department for Transport (DfT), conducted last winter, has still not been published.
The BBC reports the government is planning to launch a new assessment of the causes and remedies of the bright lights, and will include new measures in its upcoming Road Safety Strategy.
Drivers have complained that its the issue of brighter LED headlamps in new vehicles that are causing temporary blindness.
"Some of the lights are so bright you are blinded by them, for seconds," one driver told the BBC.
A new survey from the motoring organisation, the RAC, has found that more than a third of drivers are nervous about driving as the evenings get darker.
Three quarters said driving was getting more difficult because of the brighter lights.
The RAC's senior policy officer, Rod Dennis, said so far little progress has been made on tackling glare.
The results of the government commissioned research have been delayed since summer but is expected to be released within weeks.
