Abstract
Aspects of the disclosure provide a lighting apparatus for a vehicle and a method for color assurance of the lighting apparatus. The lighting apparatus includes a first lighting system and a lighting system controller. The first lighting system includes a first lighting device configured to emit first light in response to a first driving power, and a first color sensing device configured to generate a first color feedback signal that is indicative of a first color of the first light that is emitted by the first lighting device. The lighting system controller is configured to generate the first driving power to drive the first lighting device based on the first color feedback signal to ensure the first color satisfying a color requirement.
