However, if you are the proud owner of a Bang Lamp, then all you need to do is to point the provided gun towards the lamp and click the trigger. The light will shut off instantaneously. The manufacturers of this cute gadget have also included some extras. When you click the trigger, apart from the light shutting off, the lamp shade will tilt as well, as if a bullet hit it.
