PURPOSE: To prevent lighting resulting from malfunction by receiving a voltage signal outputted from a vibration sensor so as to control the supply of current to a lamp from a power source. CONSTITUTION: A control circuit 2 receives a voltage signal from a vibration sensor 4 so as to control the supply of current flowing to a lamp 3. Thereby, the lamp is not allow to light in the case of overcurrent flow or in the case of the slight touch of a conductive body to a housing case. A vibration strength or a vibration direction to which a touch light responds is freely specified by selecting the characteristics of the vibration sensor 4, or selecting a position to which the sensor 4 is fitted. |
