Firefly Pendants are one of the types of collectibles found in The Last Of Us. You need to find all these pendants in order to receive the "silver trophy Look For The Light." In total, there are 30 Firefly Pendants throughout the different chapters. You can see which pendants you have in your current game by looking in your "collectibles" menu. Any pendants you have found across all playthroughs will show up on the stats list on the main menu, and this is the count that applies to the trophy.
