1. A method of fabricating an illumination device, the method comprising:
coupling a light emitting diode (LED) array with a driver;
coupling the driver with an image frame buffer configured to store data to control driving of the LED array by the driver;
coupling the image frame buffer with a standby image frame buffer configured to store standby vehicle image data; and
coupling a processor to the frame buffer, the processor configured to use instructions to:
determine whether valid vehicle image data is present in the image frame buffer; and
in response to determining that valid vehicle image data is not present in the image frame buffer, control the image frame buffer to load the standby vehicle image data and control the driver to drive the LED array using the standby vehicle image data to generate an image.
