Car headlight is the lamp that illuminates the road in front of the car when driving at night, it can emit two kinds of beams of light: far light and near light. High light is used when there is no traffic or when the car is traveling at a high speed. Far light should ensure that in front of the car 100m or farther on the road surface to get bright and uniform lighting. Short-cut light is used when meeting cars or driving on the city's bright roads.
