Reflective address signs, unlike many street signs must be viewed at close proximity – to read your address number. Additionally, your reflective street number sign is typically seen at the level of the vehicle’s headlights. These, along a number of other factors, tend to exaggerate the halation effects of a reflective sign. A solid reflective background (such as seen in the green sign above right) can overwhelm the viewer. The entire sign glows brilliantly. Although EMS workers can easily spot the sign (say, from 400 feet away), they cannot easily decipher the actual address as they get closer to the reflective address sign.
