Candles are lit for all 8 nights of Hanukkah.

Each night of the 8 nights of Hanukkah, the candles are lit. 2 candles are lit on the first night, and then each night an additinal candle is lit until all 9 candles are lit on the 8th night.

If you would like to know when Jews burn candles, there are two major ritutal uses for candles in Judaism: a candle is lit for the Sabbath on Friday at sundown, and a series of candles are lit for the menorah during Hanukkah.
