How are the candles lit?
The first night, the first candle is lit. It is the candle on the extreme right of the menorah. On the second night, the second candle (the new one) is lit first and then the one which was lit the previous night is lit. The same is true for the successive nights, the new candle is given preference over the candles that have been lit, just like you should give preference to a new guest who is visiting you over a guest who has been by you many times before.
