Headlight Illumination Distance Requirements

Dec 08, 2018

In order to ensure safe driving, the driver must be able to identify any obstacles on the road within 100m of the front of the car. The illumination distance of the car's high beam is required to be greater than 100m. This data is based on the speed of the car. As the speed of modern cars increases, the requirements for illumination distance will increase. The illumination distance of the car's low beam is about 50m. The location requirements are mainly to illuminate the entire road surface within the illumination distance and not to deviate from the road two points.
