The distribution of light from low-beam headlamps is asymmetrical. If you go to a country with opposite traffic direction, this asymmetrical distribution will dazzle drivers in oncoming vehicles. To avoid dazzling other drivers, ECE regulations require various technical solutions (e.g., automatic change system, adhesive sheet, downward aim). This vehicle's headlamps are designed not to dazzle oncoming drivers. Thus, you need not change your headlamps when in a country with opposite traffic direction.
