Abstract:
1. A vehicle headlamp apparatus comprising: a first lamp configured to selectively produce a first high beam light distribution pattern and an infrared light distribution pattern, the first lamp switches only between the first high beam light distribution pattern and the infrared light distribution pattern; a second lamp configured to selectively produce a second high beam light distribution pattern and a low beam light distribution pattern, the second lamp switches only between the second high beam light distribution pattern and the low beam light distribution pattern; a vehicle detector which detects a vehicle running ahead based on received infrared light; a condition-dependent selection controller which controls the first and second lamps; and at least one switch which is manually operable to select one of a low beam mode, a high beam mode, and a condition dependent mode comprising a first condition dependent mode and a second condition dependent mode, wherein the condition-dependent selection controller controls the first lamp to produce the infrared light distribution pattern irrespective of whether the vehicle detector detects a vehicle and the second lamp to produce the low beam light distribution pattern irrespective of whether the vehicle detector detects a vehicle if the low beam mode is being selected; and the condition-dependent selection controller controls the first lamp to produce the first high beam light distribution pattern irrespective of whether the vehicle detector detects a vehicle and the second lamp to produce the second high beam light distribution pattern irrespective of whether the vehicle detector detects a vehicle if the high beam mode is being selected, if the first condition dependent mode is selected, if the second condition dependent mode is selected,
