Abstract: One possible embodiment of the invention could be signage illumination apparatus comprising a body, the body having generally an inverted U-shaped cross section substantially forming a channel that allows the device to straddle a support arm of a yard signage, the body generally supporting electronic circuitry that is substantially electrically connected to solar power cell(s), a rechargeable electrical storage device(s) and an illumination source(s). When light is generally energizing the solar power cell(s), the electronic circuitry may cause the resultant current from the solar power cell(s) to generally charge the rechargeable electrical power source(s) and not power the illumination device(s). When light is not generally energizing the solar panel(s), the electronic circuitry board may cause the charged rechargeable electrical power source (s) to discharge and power the illumination device(s) to illuminate at least a portion of the yard signage.
