5.7.1. Overview

The Head Light Manager (HeaLiMgr) software component is responsible for controlling the exterior lighting of the vehicle, specifically the low beam and high beam headlights. It processes inputs from various sources such as the light sensor, headlight stalk, remote headlight requests, and crash notifications to determine the appropriate headlight state. The component also handles the welcome and bye lighting actions.
