A lamp for the rear of a vehicle is disclosed with a light transmissive cover having a red first illuminated surface area and a clear second illuminated surface area. It has a first LED light emitter located directly beneath the red first area, a second LED light emitter located directly beneath the clear second area, and a third LED light emitter, also located directly beneath said clear second area. The third red LED light emitter is for emitting red light through the clear second area simultaneously with light transmitted through the red first area, whereby the first and second areas are adapted to collectively form a contiguous red illuminated surface area.
