A vehicle lamp tool 1 provided with: a controller 12 which calculates the luminance distribution of light distribution pattern; an optical device 2 which generates light distribution pattern in an illuminatable area D; and a first driving circuit 14a which drives the optical device 2. The controller 12 transmits a first light distribution correction signal for correcting the inclination of a current light distribution pattern to the first driving circuit 14a if the inclination angle of a vehicle with respect to vertical direction indicated by a detection signal received from a vehicle height sensor 18 is equal to or less than a threshold value. The first driving circuit 14a transmits a first correction driving signal based on the first light distribution correction signal to the optical device 2. The optical device 2 drives an LD 6 and a light deflector 7 to correct the current light distribution pattern.
