Tiny remote controlled switch for LED light bulb

Does anyone know where I could acquire a remote controlled on/off switch the size of a dime (or smaller) that could be used to open and close the circuit between a 3 volt CR2032 battery and an LED bulb? See photo at link below for a visual on what I am looking for. The remote control would only need to have two buttons (on and off) and a very short range.
