1. A vehicle lighting system configured to output light for a vehicle headlamp, the vehicle lighting system comprising:
a light-emitting diode (LED) circuit comprising a set of LEDs arranged in a formation for the vehicle headlamp, wherein the set of LEDs comprise a plurality of LED clusters, each LED cluster of the plurality of LED clusters comprising two or more LEDs of the set of LEDs; and
a controller configured to:
control, according to a first LED control mode via a first interface between the LED circuit and the controller, whether each LED of the set of LEDs is turned on or turned off in the first LED control mode to define a first lighting output of the vehicle headlamp; and
control, according to a second LED control mode via a second interface between the LED circuit and the controller, whether each LED cluster of the plurality of LED clusters is turned on or turned off in the second LED control mode to define a second lighting output of the vehicle headlamp, wherein the second lighting output of the vehicle headlamp is different than the first lighting output of the vehicle headlamp,
wherein the first LED control mode causes the controller to use a first amount of computing resources, wherein the second LED control mode causes the controller to use a second amount of computing resources, and wherein the second amount of computing resources is lower than the first amount of computing resources.
