A device is provided for enhancing the realistic appearance of flames produced by a simulated fireplace (gas or electric) by providing additional ambient lighting effects in response to sensed light intensity within the fireplace. The device includes a photosensor, a control circuit, and display lighting. The photosensor senses the level of light intensity produced by a simulated flame source and changes its resistive value accordingly. The control circuit has circuit parameters which uses the resistive value of the photosensor to determine whether to apply operational power to the display lighting. The display lighting consists of at least one lamp positioned above the simulated fuel bed. When simulated fireplace is operational, the display lighting of the device produces a "flickering" effect that is synchronized with the changes in light intensity occurring within the fireplace. The resulting ambient lighting effect realistically mimics the changes in light intensity that normally occur above the flames of a real wood burning fireplace.
