Candle

Candles are a light source that come in 17 different variants, one uncolored and 16 colored, that follow the general colors of wool. Candles can be lit with flint and steel and extinguished by water or by the player. They can also be waterlogged, but are unable to be lit while waterlogged.

Obtaining
Candles can be mined using any tool, or without a tool.

Light
Candles can be used as a light source, emitting light like a sea pickle. Up to four similarly-colored candles may be placed in one block, with each candle increasing the emitted light level by 3. They emit fire particles.

Candles are not lit when they are placed, and must be lit using flint and steel, fire charge, or any flaming projectile. Candles may be waterlogged, but waterlogged candles cannot be lit. Candles can be unlit using water or by the player with the candle.

Cakes
A single candle of any color may be placed onto an uneaten cake, after which it acts as a normal single candle. Only one candle may be placed on a cake. If the cake is eaten, the candle falls off.

Trivia

 * Candles are similar to the concept of burnt-out torches from the Halloween Update.
