Abstract
A circuit for compensating for failure of a light source includes a first light source having a first function and a first intensity associated therewith and a second light source having a second function and a second intensity associated therewith. A controller is connected to the first and second light sources, for detecting a current to the first light source. Upon detection of a failure of the first light source, the controller modulates the second light source to provide the function of the first light source with a substantially the first intensity.
