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