1. A vehicle lighting device comprising:
- at least two light source units for emitting light, whereby light emitted from the light source units is made to travel forward to form a high beam light distribution pattern; and
a detector for detecting an object which lies in front of the subject vehicle,wherein the high beam light distribution pattern has at least two illumination patterns which illuminate areas which are different from each other,wherein one of the at least two illumination patterns is illuminated by one of the at least two light source units and another of the at least two illumination patterns is illuminated by another of the at least two light source units,wherein a control unit is provided for controlling the at least two illumination patterns to be selectively turned on and off by selectively turning on and off at least one of the at least two light source units,wherein the control unit controls the at least two illumination patterns to be selectively turned on and off according to a detection result of the detector.

Abstract
A vehicle lighting device includes a light source unit for emitting light for forming a high beam light distribution pattern by projecting forward light from the light source unit. The high beam light distribution pattern has at least two illumination patterns which illuminate areas which are different from each other. A control unit is provided for controlling the at least two illumination patterns to be turned on and off selectively.
