<p>PROBLEM TO BE SOLVED: To surely eliminate the erroneous recognition of a lighting state by a driver. SOLUTION: A disconnection detecting means 4 and relays 6 and 7 are provided respectively in power supply lines 31 and 32 for stop lamps 21a and 21b and tail lamps 22a and 22b in both left and right sides. When a tail lamp switch 13 is turned ON and the disconnection detecting signal of the tail lamp is outputted, the relay 7 is turned ON by a lighting control means 18 to cut off the power supply line 32, and the relay 6 is turned ON to switch power supply to the stop lamp to a power supply line 33 via a luminance adjusting means 5. Changing and adjusting are performed by the luminance adjusting means 5 to reduce the light of and light the stop lamp by the same luminance as that for the tail lamp. When switches 12 and 13 are OFF, LED 911 to 914 are turned OFF by a display control means 19, LED 911 and 913 are lit by green color to perform normal displaying when the switch is ON and no disconnection detecting signals are outputted and, when a disconnection detecting signal is outputted, LED 912 and 914 are lit by red color to display abnormality and simultaneously sound an alarming buzzer 92.</p> |
