A headlamp control apparatus (100) controls a vehicular headlamp, including a plurality of LEDs (34R/L-1 to 34R/L-20), that is capable of altering brightness partly in an irradiated region according to an operation mode. The control apparatus (100) includes: a mode information reception portion (108, 116) that receives, via a first communication line LIN, mode information (200), indicating an on/off state of the operation mode, that specifies a portion of the irradiated region, in which brightness needs to be altered, if the operation mode is on; a state determination portion (110, 118) that determines a state of each LED based on which portion of the irradiated region is specified by the received mode information, if the mode information indicates that the operation mode is on; and a light source control portion (112, 120) that controls the LEDs (34R/L-1 to 34R/L-20) so as to cause each LED (34R/L-1 to 34R/L-20) to be brought into the state determined by the state determination portion (110,118).
