Grenade, Flare (5e Equipment)
From D&D Wiki
Martial Ranged Weapons
Flares are held, thrown, or fired devices intended for increasing visibility, rather than to create casualties.
As an action, you can throw a flare grenade at a point up to 60 feet away. Each creature within 5 feet of an exploding flare grenade must make a DC 15 Dexterity saving throw or take 1d6 fire damage. On a successful save, a creature takes half damage. A thrown flare grenade sheds bright light for 60 ft., and dim light for another 120 ft. for 1 minute.
