An illumination device according to the present invention generally includes a housing, electrical plug prongs, a connector portion associated with the housing for receiving and electrically contacting a light bulb, and a heat sensitive electrical circuit for conducting electrical current from an electrical outlet or other electrical power source to a light bulb received within through the connector portion of the illumination device. Preferably, the heat sensitive electrical circuit includes a bimetallic strip or other heat sensitive mechanism that automatically interrupts the flow of electrical current through the connector portion of the night light when the temperature sensed by the bimetallic strip exceeds a predetermined temperature level. In another embodiment of the present invention, an illumination device is equipped with a successive heat sensitive switching mechanism, in which the power conducted to the light bulb is initially reduced in response to ambient temperature levels exceeding a first predetermined temperature level, with the flow of electrical current to the light bulb being interrupted only in response to a second, higher predetermined temperature level.
