The function of this laser fog light is similar to that of smart taillight.It is composed of laser diode at the back of the car and emitted a bright and clear signal which tells motorists not to get close.
If the visibility is good,it produces fan beam projecting on the ground. When the beam touches the ground,it turns a red line,alerting the vehicles not closing. The width of this line depends on the distance between cars. For example,from 30 meters away to look,the width equals that of car ,just like a stop line, warning motors keeping a safe distance.
