Abstract: A circuit may be configured to control a vehicle headlamp comprising light emitting diodes (LEDs). The circuit may comprise an LED controller configured to receive video data from a video source via a first interface; an LED driver configured to drive the LEDs based at least in part on the video data; and a second interface between the LED controller and the LED driver, wherein the second interface is configured to communicate the video data from the LED controller to the LED driver and wherein the second interface communicates the video data at a slower data rate than the first interface.
