    • Left and right turn lamps are used as lamps in a daytime travel of a vehicle. When a first daytime turn-on requirement is satisfied, i.e., when an ignition switch is ON, a left-hand contact of a turn switch is OFF, a right-hand contact thereof is off, and the like, a left front turn lamp and a right front turn lamp are turned on as the lamps in the daytime travel, based on signals outputted from first and second AND logic circuits. When the left-hand contact of the turn switch is turned on in this state, the left front turn lamp flashes, based on a signal outputted from a flasher circuit, whereas the right front turn lamp keeps a turn-on state. On the other hand, when the right-hand contact of the turn switch is turned on, the right front-turn lamp flashes, based on a signal outputted from the flasher circuit, whereas the left front turn lamp keeps a turn-on state.

    • A flasher circuit included in a vehicular turn signal indicator system has a flashing control circuit, a flashing relay, a current detecting resistor, and a switching circuit. The control circuit detects a voltage drop across the resistor during driving of light bulb indicator lamps and light emitting diode (LED) indicator lamps of the system. Each LED lamp is configured to output a disconnection signal if at least one of their LEDs is disconnected during the driving. The signal turns on a transistor of a switching circuit, resulting in short across the resistor. As a result, the voltage drop is lowered equal to or under the threshold value, and the control circuit starts the disconnection detection.

    • An electronic circuit device has a current correction circuit that supplies a correction current which is capable of offsetting an increment or a decrement of a consumption current of a signal processor circuit that varies based on a signal level of an input signal. Therefore, even if the consumption current of the signal processor circuit varies based on the signal level of the received input signal, the variation of the consumption current is offset by the current correction circuit. As a result, even if the consumption current varies based on the signal level of the input signal, since a current that flows in a resistor does not vary, a voltage drop can be held constant. Accordingly, it is possible to accurately conduct a comparison determination by a comparator.
    • 电子电路装置具有电流校正电路,其提供校正电流,该校正电流能够抵消基于输入信号的信号电平而变化的信号处理器电路的消耗电流的增量或减量。 因此,即使信号处理电路的消耗电流根据接收到的输入信号的信号电平而变化,消耗电流的变化被电流校正电路偏移。 结果,即使消耗电流基于输入信号的信号电平而变化,由于在电阻器中流动的电流不变,所以可以保持电压降恒定。 因此,可以通过比较器准确地进行比较判定。
