Abstract: A nightlight comprises a body having a press button; a base arranged on the body and having a round engagement basin at a central region thereof; a rotatable plug arranged between the body and the base and including a round positioning engagement block arranged on a front side thereof and accommodated by the round engagement basin and two conductive insert plates penetrating the round positioning engagement block; and a light emitting element arranged in the body. The positioning engagement block is rotatably engaged with the engagement basin, whereby the rotatable plug can rotate with respect to the base by 360 degrees. Further, only the ends of the first and second conductive insert plates are exposed outsides, whereby is reduced the size of the nightlight and decreased the number of the components.
