Abstract
An indication lamp for, for instance, aircraft passenger cabins comprising light sources housed in lamp chambers defined by a housing and a front cover. Translucent indication portions of the shapes indicative of non-smoking and fasten-seatbelt signs in red, for instance, are formed in the front cover; and the light sources, each comprising a set of light emitting diodes of different colors, such as green and red, are installed behind the translucent indication portions so that each light source emits a mixture of colors that is similar to an incandescent light, thus illuminating the sings with an enhanced visibility.
