Abstract
A single LED combined with a dark-colored reflective cavity, a diffusing graphic overlay, and a dark tinted window, provides a backlighted indicator with low power requirements. The design exhibits high visual contrast between on and off conditions, giving daylight visibility. The diffusing overlay and the window are nested and individually attached to a housing with adhesives, thus providing a double barrier against liquid penetration. Thus, the indicator can be used outdoors and under conditions of limited power. For example, the indicator may be part of a customer terminal mounted outdoors at retail establishments, such as gasoline stations.
