REGULATION OF ELECTRONIC MESSAGE DISPLAY SIGNS Overview We are all very fortunate to live in a society that places a premium value on freedoms, and limits governmental intrusion upon those freedoms. Freedom of speech is one of those essential freedoms, and one that is embodied within the Constitution that molds the rule of law governing this great nation. Many reputable organizations, like the U.S. Small Business Administration and the International Sign Association caution against sign regulations that interfere with the freedom of exercising commercial speech. The following information has been assembled by a coalition of manufacturers of electronic message display signs. We recognize the uncertainty surrounding the legality of certain sign regulations. We also respect the desire by communities to regulate signs, including electronic message display signs, and the need for responsible sign codes. Without engaging in debate over the legality of regulations affecting electronic message displays, the following materials are intended to develop a more sophisticated understanding of the current state of the technology, and to promote regulations that reflect the broad variations in the use of electronic message displays. The History of Changeable Message Signs In the day when signs were primarily painted, changing messages on a sign merely required painting over the existing message. More recently, signs with removable lettering made it possible to manually change the lettering on a sign to display a new message. Electrical changeable message signs followed the invention of the light bulb, and included light bulbs arranged in a pattern where, by lighting some light bulbs and not the others, letters and numerals could be spelled out. With the advent of solid-state circuitry in the early 1970s, electronic changeable message signs became possible. The first of these products were time and temperature displays and simple text message displays using incandescent lamps. These lamps were very inefficient. They used a great deal of power and had short life expectancies. During the energy crunch of the 1980s, it became necessary to find ways to- reduce the power consumption of these displays. This. need initially spawned a reflective technology. This technology typically consisted of a light-reflective material applied to a mechanical device, sometimes referred to as "flip disk" 27-
