The German Road Safety Council (DVR) have issued six recommendations to reduce headlight glare to road users and improve traffic safety:
- Automatic levelling devices should be mandatory for all headlamps. The DVR support the proposed amendment to UN Regulation № 48 on the mandatory installation of automatic headlight range control for all headlamp systems.
- The cleaning performance of conventional headlight cleaning systems is not comparable to manual cleaning. Vehicle manufacturers and suppliers should make efforts to improve the effectiveness of cleaning equipment.
- ADB should be mandatory. The legal requirements must be adapted in such a way that the detection and suppression of all oncoming glare is ensured by glare-free high beams.
- It is recommended to evaluate the potential of modern lighting technology in the Euro NCAP ranking, such as by using the HSPR (Headlamp Safety Performance Rating) protocol.
- Further accident research is needed on the question of the contribution of modern lighting technology to road safety and the influence of glare on vulnerable road users.
- As luminance increases with smaller headlights, the BMDV (German Federal Ministry of Transport and Digital Infrastructure) should advocate for the regulation of luminance at the international level. Same with the blue component in LED headlights which can cause unpleasant glare and potentially damage the photoreceptors of the human eye over a long period of time.
