In a vehicle headlamp that uses a light source having high output intensity, turn off the light source quickly when an abnormality occurs. A lighting control device of a vehicle headlamp includes a lighting control part that controls an on state of the vehicle headlamp, an obstacle detecting part for detecting an obstacle that exists in front of the vehicle, and a collision prediction processing part that, when the obstacle exists on the basis of detection results from the obstacle detecting part, predicts a possibility of collision between the obstacle and the vehicle on the basis of a distance between the obstacle and the vehicle and a speed of the vehicle and, when it is determined that the possibility of collision exists, instructs the lighting control part to relatively decrease an output light of the vehicle headlamp to below a normal intensity of the vehicle headlamp.
