Abstract: A remote controlled vehicle display system including a remote activator having an activator body and an input device adapted to receive a user input. The remote actuator further includes a transmitter adapted to generate a wireless activation signal in response to receipt of the user input. A display device is attachable to a vehicle and includes a housing including a slot formed therein. A receiver is coupled to the display housing, and is adapted to receive the wireless activation signal from the transmitter. A light source is coupled to the housing and is in operative communication with the receiver, with the light source being activated in response to receipt of the wireless activation signal by the receiver. A display insert is selectively insertable within the slot formed within the housing so as to be illuminated by the light source when the light source is activated.
