Abstract
A flashing advertising sign is provided for indoor use. The sign is of box-like transparent construction having parallel front and rear panels and elongated upper and lower panels having facing retaining channels which slidably secure a flat placard. Photovoltaic cells positioned in the upper panel supply energy to a rechargeable storage battery. A timing circuit periodically directs electrical current from the battery to light-emitting diodes which illuminate the placard.
