An edge lighted display sign is disclosed which provides a base portion, defining a housing for a light source and a variable duty cycle oscillator including an exteriorly disposed ratio control device whereby the light source may be controlled from an "off" position, through an "on" "off" blinking range, from a very slow to a very rapid blinking, to a completely "on" position. A longitudinally extending slot is provided along the top length of the base to receive a lower end length of a transparent panel, formed of a clear or translucent glass or a suitable plastic material, whereby the lower edge portion of the glass panel is directly exposed to the light source. In a preferred form, the light source comprises a fluorescent light tube, and a removable bottom panel is provided for the housing to permit access to the light source and the cycle oscillator. A back side of the transparent panel is provided with an opaque coating or covering. Alternatively, the back side may be frosted. The front side of the panel is adapted to receive any type of message, advertising or the like in contrasting colors to the opaque back side. The messages, advertising, etc. may be of a removable or permanent nature.
