Flares are an item in Rust. Flares are used to create a source of temporary light at night so that players can navigate the world. Players can hold a lit flare (left mouse button with flare equipped) in their hand to create a mobile source of light which moves with the player, or players can light a flare and throw it (right mouse button with flare equipped) to create a stationary source of light which remains static in the world.
As with all light sources, the flare poses the risk of making it easier for enemies to see the user.
Flares can be thrown and light up an area without the item being held, hopefully making the enemy visible and creating glare, for nightly raids or engagements of any kind during nighttime.
Flares can be thrown into the air to signal teammates to a place where the team could regather (a rallying point).
A thrown flare lasts for approximately 2 minutes.
Flares are mainly only used to gain gun powder from recycling or to light up a dark cave.
Flares thrown into water will be extinguished.
