The Replacement Bulb is an item required for the "Cinéma Vérité" sidequest in Silent Hill: Downpour. It is used to fix the projector in the Chastain Heights Cinema. Depending on the puzzle difficulty, the bulb can be found in two different locations.
There are two different locations it can be in, dependent on difficulty:
- On Easy mode, the bulb can be found in the poster storage room located at the back of the cinema.
- On Normal and Hard mode, the bulb is located east of St. Maria's Monastery and can be found on a shelf behind a counter in the hardware store.
