Candle

Candles are items that have appeared only twice in the Zelda series. They are usually used to light up dark areas, such as a dungeon room or a cave. Later titles have replaced the candles with similarly functioning lanterns.

Location
In The Legend of Zelda, there are two obtainable candles, the Blue Candle and Red Candle. In both quests (First and Second), the former can be purchased in several overworld shops for sixty or more Rupees, and the latter is found in the seventh level, Demon Labyrinth.

Uses
When used, either will shoot a fire ball a few tiles ahead of Link, which will remain for a few seconds before disappearing. Although the flame's main function is to light up dark rooms in certain dungeons,. it will also slightly damage anyone who walks into it, including Link himself. Either candle's flame can also burn down certain bushes in the overworld to reveal hidden staircases, including those leading to Lion Labyrinth in the first quest, and Demon Labyrinth in the second quest.

The Blue Candle is capable of only producing one flame per screen. The Red Candle can produce unlimited flames.

Location and Uses
In The Adventure of Link, the Candle can be found in Parapa Palace after defeating an Iron Knuckle. It lights up otherwise pitch-black caves and allows Link to see any enemies who may dwell in a dark cave. Although it is an optional item, those without it will face difficult situations later in the game.
