All candles are sacramentals used in the Church's liturgy. The candles particular to Advent would be the candles on the Advent wreath, and these stand for the four Sundays in Advent, which is focused on penance and preparation for the coming of the Lord, both in His Nativity and in His Second Coming.
The Advent Wreath candles are lit one each on the four Sundays leading up to Christmas, the season of Advent. There are three purple & one pink. 1st Sunday in Advent light purple, 2nd Sunday in Advent light purple, 3rd Sunday in Advent light Pink, 4th Sunday in Advent light Purple (all 4 candles are now lit).
