Abstract

PURPOSE:To prevent a poor action of a circuit by lessening a voltage drop influence of a battery at the time of lighting of a lamp with the aid of turning on the switch of the lamp after a given times when a switch a warning buzzer is off. CONSTITUTION:When the voltage of battery is lower, if a buzzer is operated through a driving circuit 7, the voltage is more lowered. At the time, when a switch for buzzer stopping 6 is on, a signal is input to a reset terminal 5, thereby inputting a signal to a delay circuit 9 together with stopping the buzzer. The switch 10 is closed by the output of this delay circuit 9 and lamp 3 is lighted. Thus, the voltage of the battery 3 can be prevented from an abnormal decreasing by the flowing current to the lamp 3.
