A vehicle lamp system includes lamps RHL and LHL. The lamp system can switch at least to a low beam distribution and a motorway light distribution. A light distribution switching control portion CONT for switching the light distribution based on operational information of the vehicle switches to the low beam distribution when it is determined that the vehicle speed is less than a predetermined speed in the motorway light distribution and a predetermined light distribution switching condition is satisfied. If presence of an obstacle is confirmed so as to apply a deceleration, it is possible to prevent the obstacle from being undetected by switching to the low beam distribution. Thus, it is possible to reliably keep away from the obstacle, thereby ensuring stable operation.
