Flashlights can be toggled on and off by the player. When in use, the flashlight will illuminate a cone-shaped area in front of the player. While a flashlight is on it will slowly lose charge until it runs out. Upon inserting a single battery, the flashlight can be used for 45 more seconds.
Flashlights are one of the most effective light sources in the game, being easily controllable with a high charge time while also being easy to obtain.
Flashlights are reusable and are not removed from the player's inventory after running out of charge, instead being rendered unusable until recharged.
The light from a flashlight can anger Squiddles, causing them to attack.
