Flare (Subnautica)

Flares are tools that are crafted with the Fabricator.

This allows the player to illuminate dark areas like caves with a stationary light source, thus making it easier for the player to defend themselves or to spot resources.

Two of them can also be found in the storage within Lifepod 5 at the start of the game.

While flares are supposed to burn eventually, most of them never burn out, burning forever. This is clearly a bug, as they are meant to burn out, but never do.

Uses
Flares can be ignited and thrown by selecting it from the toolbar and pressing (Xbox One:

, PlayStation 4:). This will cause the player to throw the Flare slightly forward, and then it will sink until it hits another object.

The player can also pick up a Flare after it has been ignited. The ignited Flare stays lit when in the players hand, illuminating an area around the player.

The Flare will not despawn. Because of this, the player can regularly throw a Flare when exploring an intricate cave system. If the player needs to leave they can simply follow the trail of Flares back to safety.

Because some hostile creatures, such as Bonesharks or Crabsquids, are attracted to light sources, the player can toss a Flare so that it sinks away from the player, thus distracting the creature.
