Referring to FIG. 12, ear 96 has an upwardly and outwardly inclined edge 96A and an upper inwardly directed edge 96B. Each ear 97, 98, and 99 has similar edges indicated by the same reference numerals having the suffixes A and B. The edges 96B-99B are longitudinally spaced from flange 73 to provide gaps or throats 101. The throats 101 have a thickness that is substantially the same as the thickness of the enlarged shoulders 60 of top wall 38. Portions of the shoulder 60 extend between adjacent slots 76-79 and friction fit into throats 101 to releasably mount light information unit 28 on top wall 38. The casing 66, walls 71 and 74, flanges 76-79, and ears 96-99 are a one-piece plastic unit. Other materials can be used in the construction of information unit 28.
In use, cap 89 is turned onto the casing to effect an electrical connection between battery 68 and base 84 and light bulb 83. This completes the electrical circuit to light bulb 83, thereby causing the light bulb to intermittently turn on and off or flash. Casing 66 and cap 89 are moved longitudinally downward through hole 54 in top wall 38. Ears 96-99 are aligned with slots 56-59. When flange 73 engages top wall 38, the entire light information unit 28 is rotated until ears 96-99 engage lugs 61-64. As shown in FIG. 5, ears 96-99 are in engagement with the sides of lugs 61-69.
Light information unit 28 is removed from the top wall 38 by rotating the unit in an opposite direction to align ears 96-99 with slots 56-59. This releases the holding action of ears 96-99 on shoulder 60 of top wall 38 and allows the entire light information unit 28 to be vertically removed from support 26.

A circular member or flange 108 is integral with the central section of the bottom of frame 106. Gusset members or ribs 109 and 110 join flange 108 to the sides of frame 106.
A tubular member or cylindrical body 112 projects downwardly from the bottom of flange 107. Body 112 has a plurality of outwardly directed ears 113, 114, 115, and 116. The upper edges of ears 113-116 are spaced from the flange 108 to form throats 117. The throats 117 have approximately the width of the thickness of the shoulder 60 on the top wall 38, whereby the top wall has a friction fit between ears 113-116 and flange 108. Ears 113-116 are circumferentially oriented from each other with the same circumferential orientation as slots 56-59 in top wall 38. This orientation is the 90 degree relationship between adjacent ears, as shown in FIG. 19. The entire sign information unit 103 is preferably made of plastic. Other types of materials can be used in the construction of the sign information unit 103.
In use, sign information unit 103 is attached to top wall 38 by placing the tubular member 112 in the hole 54 in top wall 38. The lower surface of flange 108 rests on top wall 38. The ears 113-116 are aligned with slots 56-59. The entire sign information unit 103 is turned about an upright axis approximately 45 degrees or until ears 113-116 engage lugs 61-64, depending from top wall 38. As shown in FIG. 14, when sign information unit 103 is mounted on top wall 38, the flat plane of the board 104 is located in general parallel alignment with side walls 30 and 32. This allows information on the side walls 30 and 32 to be coordinated with the printed symbol and word information carried by the board 104.
Sign information unit 103 is removed from support 26 by rotating unit 103 in a direction to move ears 113-116 away from lugs 61-64 and aligning ears 113-116 with slots 56-59. The entire sign information unit 103 is then withdrawn vertically from top wall 38. A second sign information unit containing appropriate printed information can be mounted on top wall 38. Alternatively, light information unit 28 can be mounted on top wall 38.
Light unit 28 and sign unit 103 can be replaced with a circular container unit having a flange, tubular member, and ears adapted to be mounted on the top wall 38 of stand 26, as described with respect to light unit 28. The container unit can be a box, a circular disc-shaped member, or ash tray.
