Zusammenfassung:A vehicular lamp system (1) includes a light distribution control device (8) that controls a first lamp unit (2) and a second lamp unit (4). The light distribution control device (8) forms a combined high-illuminance pattern (42) in a region where no target is present. Meanwhile, the light distribution control device (8) forms a combined shading pattern (40) in regard to a forward vehicle (V). Furthermore, in regard to a specific target (A), the light distribution control device (8) controls the first lamp unit (2) so as to form an illuminance fixed pattern (46), controls the second lamp unit (4) so as to form an illuminance fixed pattern (46) or to form an illuminance adjusted pattern (48), and forms a combined mid-illuminance pattern (44) by superposing the light distribution patterns that the first lamp unit (2) and the second lamp unit(4) form.
