Abstract
A vehicle headlight system can include a headlight controller and a lamp unit incorporating a high beam module, which can emit favorable marking lights while the headlight controller associates each of a shading driver and a swivel structure with a shading width setter and a swivel setter, respectively. When a forward vehicle does not exist in a forward direction, the headlight systems can provide favorable light distribution patterns by overlapping the light distribution pattern projected from the high beam module with each of light distribution patterns for a high and low beam. When the forward vehicle exists, the headlight system can prevent the lamp unit from emitting a glare type light to the forward vehicle. Thus, the disclosed subject matter can provide vehicle headlight systems, which can emit favorable light patterns toward a pedestrian as a marking light, and which can provide favorable light distribution patterns to drive at night.
