The light advertisement system includes transparent covering shells (4) for light advertisement elements and lightproof installation carriers (8) which are connected to the side stud of the covering shell. A frame (9) formed from vertical braces (10) and horizontal braces (11) is arranged between the covering shells and the installation carriers. The covering shells are connected at the front (12) of the frame and the installation carrier are connected at the back (13) of the frame. The distance between the front and the back of the frame is so big that a person can move in the spacing (16) between the sides. The distance between centres of adjacent vertical braces or adjacent horizontal braces is the same as the length or the hight of the covering shells. Neon lamps (23) are arranged bevelled to the vertical or horizontal braces.
