<p>PURPOSE:To discover trouble of an indicating device surely and quickly by providing a plurality of direction indicator lamps outside the vehicle body, and providing a monitoring and displaying device for them in a driver room. CONSTITUTION:In the proximity of a driver's seat, a display plate 20 arranged with light emitting diodes 3, 9-19 of which lighting is interlocked with indicator lamps, corresponding to the arranged positions of the indicator lamps fitted outside the vehicle is provided. For example, a circuit is constituted so that a resistance 2 connected to a light emitting diode 3 in parallel, and a direction indicating switch 4, an electric switch 5 automatically breaking and making with a prescribed period independent of variation of number of actuated indicator lamps, and a indicator lamp 1 are connected together with. By this constitution, breaking of wire in the indicator lamp 1 is displayed by existence or none of lighting of the light emitting diode 3. Thus, trouble of the indicating device can be early discovered.</p> |
