摘要： PROBLEM TO BE SOLVED: To prevent a light source from non-lighting, even if a braking decision means for deciding a braking state or a steep braking state of a vehicle becomes an abnormal state. SOLUTION: A CPU 32 takes signals from a vehicle speed sensor 48, a hazard circuit 52 and a stop circuit 56 in via interface circuits 24 to 30. When the vehicle is steeply braked, blinking signals are output to AND gates 36 and 38, and stop lamps 18 and 20 are blinked by lighting switches 40 and 42. When the vehicle is braked or the CPU 32 is abnormal, output terminals 66 and 68 are fixed in a high level. When the output terminals 66 and 68 are fixed in the high level when the CPU 32 is abnormal, a condition of an AND of the AND gates 36 and 38 is established when outputs of interface circuits 28 and 30 becomes the high level, and lighting switches 40 and 42 continuously light up the stop lamps 18 and 20.

摘要： PROBLEM TO BE SOLVED: To provide a lighting fixture system for vehicles capable of judging the number of abnormal luminous elements and other abnormal elements within a lamp through connection of a single line between the lamp and a judgment circuit. SOLUTION: The system is equipped with a luminous unit 20, composed of the parallel connection of a plurality of luminous elements 21; a lamp TL, which is fitted with a line breakage detection circuit 22, designed to detect line breakage of individual luminous elements; and a judgment circuit 5, linked with the line breakage detection circuit with a single signal line and designed to judge abnormality of luminous elements. The line breakage detection circuit 22 outputs an electric potential corresponding to the luminous element, from which line breakage was detected, to the signal line SL, while the judgment circuit 5 passes judgment about the abnormal luminous element in line with the electric potential from the said signal line SL. Because the number of luminous elements in which line breakage occurred and their position/arrangements within the lamp cause changes in the electric potential output to the signal line, the judgment circuit 5 can judge the number of abnormal luminous elements and their location/arrangements within the lamp.
