PURPOSE: A broadband auto light apparatus of a vehicle is provided to automatically light a taillight and a sidelight by using a controlling part which controls the lighting of the taillight and the sidelight based on the determination result of the controller. CONSTITUTION: An optical sensor(10) senses an external luminance. A standard control part(30) determines a clear day and a cloudy day by comparing the luminance value and a predetermined upper limit value range. The standard control part controls a sidelight output part to turn on the sidelight with the taillight based on the determination result. An upper limit setting part(50) automatically changes the predetermined upper limit value range in the standard control part based on the determination result of the standard control part. A headlight control part(70) turns on a headlight by controlling a headlight output part based on the lamination value.
