Abstract
A visual signaling system including at least two light sources. Graphic indicators positioned adjacent to the light sources for identifying the light sources. The indicators including codes for identifying a particular light source with which it is associated and permitting one to distinguish one light source from another relying on the code. The indicator, in one form of the invention, may consist of a band positioned adjacent to the light source with the code being the extent of shading of the band. In one form of the invention, a circular band is provided with discrete levels of shading corresponding to particular light sources. The system may be a warning or alarm system with the extent of shading being a function of the relative importance of the particular light source.
