Abstract: A plate for attaching an accessory to a panel such as a vehicle interior headliner including a molded polymeric frame having a dimension adapted to lie adjacent and span at least one opening formed in a panel to receive the accessory. At least one clamp, pivotally coupled to the frame, is adapted to be actuated from the same side of the panel on which the frame is mounted. The clamp swings through the panel opening and engages the opposite panel surface, locking the frame adjacent the panel opening. The frame includes bosses to receive fasteners attaching an accessory such as a vehicle light. In the alternative, the frame receives a conductive bracket for receiving a light bulb or other accessory, thereby acting as the accessory itself.
