Lighter is an item in Resident Evil 0.
The Lighter is available at the start in Billy Coen's inventory, but it cannot be used until the Lighter Fluid is recovered in the Umbrella Executive Training School. It is used at two key points in the game, to light the candle in the Library, and to light the animal candles in the Basement hall.
