Flare gun

This was a device that would send a harmless flare of light into the air to signal for help when in distress. After the Battle of Alderaan (Great Galactic War) hundreds of Republic troopers shot these flares into the sky to alert the Republic Navy after their defeat of the Sith Empire (Post–Great Hyperspace War).
