A display with light elements comprises a substrate layer and a display layer. The substrate layer comprises a power source, a plurality of light elements interconnected to the power source, and a controller interconnected to the power source and light elements. The substrate layer may be formed of flexible material. The controller is operable to activate at least a first light element to a different illumination state relative to at least a second light element. The display layer is interconnected to the substrate, covers at least a substantial portion of the substrate, said contains text and/or graphics covering at least a substantial portion thereof. The display layer may be formed of flexible material. At least one of the light sources is visible through the display layer when the light source is activated. The power source may include a solar cell and/or a battery. In embodiments in which the power source comprises both a battery and solar cell, the solar cell may be used to recharge the battery to operate the light elements and controller in low light conditions.
