Abstract
An EL lamp having a transparent front electrode is overprinted with an opaque graphic having the same color as the phosphor in the lamp. A translucent coating over the graphic is clear or tinted. The graphic is visible only when the lamp is lit. In an alternative embodiment of the invention, a second graphic, visible whether or not the lamp is lit, is overprinted on the lamp. The second graphic has a color perceptibly different from the color of the phosphor and is opaque, transparent, or any opacity between opaque and transparent.
