To replace a headlight bulb in a Ssangyong Korando C206, start by opening the hood and locating the back of the headlight assembly. Disconnect the electrical connector from the bulb, then twist and remove the bulb socket from the headlight assembly. Carefully remove the old bulb and replace it with a new one, making sure not to touch the glass part of the bulb with bare hands. Reinstall the bulb socket, reconnect the electrical connector, and test the headlight before closing the hood.
