Abstract

Abstract A signal lamp for an automotive vehicle is disclosed including a housing having at least two individual signal compartments each including a light source and a common glass cover having a predetermined color. A colorless carrier disc having black opaque stripes on one side of the carrier disc and lens elements on an opposite side spans both compartments. A red color filter spans one compartment between the carrier disc and the one compartment lamp and an unsaturated light filter of a color different from the color of the glass cover spans the other compartment between the carrier disc and the other lamp. In the off condition of both lamps, the signal lamp color is determined by the color of the glass cover. The red filter produces a red signal when the one lamp is on. The combination of the unsaturated filter and the color of the glass cover produce a signal color at the second compartment when its lamp is on which is different from that of the unsaturated filter color or glass cover color and representative of a desired vehicle condition including vehicle reverse illumination, warning signal and turn signal.
