Abstract: An extruded post used to support a sign, mailbox or set of rails, or in a stand-alone mode, with an interior light source to illuminate characters cut out of the wall of the post or rail for identification of a property or to transmit a message. The light source is inserted into the interior of the post or rail. A translucent sheet is placed within the wall of the post or rail and in front of the illumination source. A reflective backing, with a locking aspect, is inserted into the post or rail to reflect light from the light source thru the translucent sheet and thru the cut out characters. Power for the illumination is provided by a solar charged battery placed in a cap on top of the post. A processing unit is placed in line between the power source and the illumination to generate light patterns and effects.
