A flashlight has a center pivot mechanical connection between a plastic battery housing and a rotatable plastic turret, permitting free rotation of the turret. A lamp housing is pivotable within the turret about an axis perpendicular to the center pivot. Electrical connection between the lamp within the lamp housing, and the batteries within the battery housing is provided by two pairs of ring and point contacts mounted to the turret and the battery housing, and by ring contacts connected to the lamp housing surrounding the pivot axis of the lamp housing which engage with a point contact and ring contact in the turret. The light may thus be pointed in any direction in the hemisphere above the battery housing. A snap ring securely retains the turret to the battery housing while permitting free rotation about the rigid center pivot which does not provide electrical connection.
