The utility model provides an integrate vehicle headlamps system of fog lamp function, including short -distance beam light source and distance light light source, the distance light light source is disposed under the short -distance beam light source, be provided with short -distance beam free -form surface lens before the short -distance beam light source, be provided with distance light free -form surface lens before the distance light light source, short -distance beam free -form surface lens and distance light free -form surface lens front portion are provided with short -distance beam baffle and distance light baffle, the short -distance beam baffle is located the position of realizing the short -distance beam, the distance light baffle is located the position of time distance light, be provided with convex lens before short -distance beam baffle and the distance light baffle. Can be at rain and fog weather, do not need to increase alone the condition of fog lamp illumination under, realize that the penetration power is stronger, the farther safe illumination of irradiating range sparingly increases the cost of fog lamp to effective body design space of saving.
