1. An apparatus for controlling a light of a vehicle, comprising:
a lighting controller area network (CAN) configured to receive, from an autonomous driving system (ADS) of the vehicle, at least one ADS message;
a vehicle electronic control unit (VECU), coupled to the lighting CAN, configured to receive a driver-initiated message; and
a chassis node coupled to the lighting CAN and separately disposed from the vehicle electronic control unit (VECU),
wherein the chassis node is configured to control lighting operations of a first lighting element and a second lighting element of the vehicle based on a control message, wherein the control message is based on a conflict resolution between the at least one ADS message and the driver-initiated message, and
wherein the chassis node is further configured to operate the first lighting element and the second lighting element using predetermined current limits such that, in response to a determination that at least one of the predetermined current limits has been exceeded, the chassis node operates in a protection mode in which the first lighting element is allowed to operate, and the second lighting element is disallowed to operate.
