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.

A vehicle lighting outage detection circuit is disclosed having a plurality of parallel branches connected at a common positive reference node. Each parallel branch comprises a branch resistor and a current controlled branch switching device connected in series. A constant current source is connected to the positive reference node and configured to deliver a substantially constant current to the positive reference node. The cathode of a zener diode is connected to the positive reference node. When current to a predetermined number of the branch resistors is interrupted due to the failure one or more LEDs connected to the control inputs of the branch switching devices, the voltage at the positive reference node increases beyond the breakdown voltage of the zener diode. In such a condition, excess current flow to the anode of the zener diode to supply an outage detection signal.
