The Lighter can be used either when held or when in the inventory. The Lighter can be lit by right-clicking while holding it. Smudge Sticks or Candles can then be lit by aiming at the item and pressing the Secondary Use key [F]. Alternatively, if the Lighter is in the inventory, Smudge Sticks or Candles being held in the hand can be lit by pressing the Secondary Use key. The Lighter does not have to be lit prior in this case.
