<p>PROBLEM TO BE SOLVED: To provide a device for detecting a disconnection of a lamp mounted on a vehicle of which cost is not increased and a detection accuracy of a lamp disconnection is not decreased even if numbers of lamps are many, and which can reliably detect a lamp disconnection even if an environmental illuminance is high.SOLUTION: Lamp identification information concerning a lamp of which lighting is instructed by a lamp lighting instruction part 51 is read from a lamp identification information storage part 54 and is outputted to a modulation part 52, and a lamp is modulated and lighted. A lamp lighting light region in an image photographed by a camera part 2 is identified by a lighting light signal acquisition part 61, lamp identification information is demodulated by a demodulation part 62 and is taken out. The demodulated lamp identification information and lamp identification information concerning a predetermined lamp of which lighting is instructed by the lamp lighting instruction part are checked by a lighting state determination part 63, whereby a disconnection of the predetermined lamp of which lighting is instructed is determined.</p> |
