A light source comprised of a transparent body and a printed circuit board is mounted to a transparent display panel. The transparent body is comprised of a series of light-collimating lenses. The printed circuit board comprises a series of LEDs which are arranged such that the emitted light enters the collimating lenses and then enters the transparent display panel. The substantially collimated light reflects within the display panel until it contacts a diffuse surface portion, causing the light to exit the display panel. The on/off state and intensity of the LEDs are controlled by a programmable device. The transparent body and transparent display panel are sufficiently flat to facilitate a layered arrangement of assemblies.
