VEHICLE HEADLIGHT FOR GENERATING BEAM FLUX HAVING WIDER RANGE THAN THAT OF LOW BEAM FLUX

摘要

PROBLEM TO BE SOLVED: To prevent a car on the opposite lane from being dazzled by recognizing a wrong operation with a control device. SOLUTION: A safety device (50), which at least indirectly watches the function of control device (28), and in the case of such an error that the control device (28) does not operate in good order, reduces the electric power making a light source (12) operate, and/or reduces the range of the light flux irradiated from a headlight incretion part, is installed.
