Abstract
A vehicle lighting device and method of transitioning color output by a vehicle lighting device are provided. The method includes activating the lighting device to output a first color light, and deactivating the first color light. The method also includes the steps of generating an intermediate color light with the lighting device for a short time period. The method further includes the step of generating a second color light with the lighting device. Accordingly, the intermediate color light prevents the apparent generation of an undesirable intermediate color light.
