How far do we go in the Chanukah Mitzvah?

MISHNAH: A spark that escapes from under a hammer and causes damage, [the one who caused the spark] is liable. A camel that was loaded with flax and was passing through the public domain and the flax entered into a store and was lit by a candle of the store owner and lit the building on fire, the owner of the camel is liable. The store owner who places his candle outside of his shop is liable. Rabbi Yehudah said:"In regards to a chanukkah candle he is exempt."

(1) During the Second Temple period, when the Hellenic kings decreed decrees upon Israel, and [sought to] nullify their religion, and they did not allow them to immerse in Torah and in commandments. And they reached out their hands against their money and their daughters, and they entered the shrine, and put in there idols, and defiled that which was pure. And was Israel was distressed because of them, and oppressed them greatly until the God of their ancestors had compassion on them, and saved them from their hands, and rescued them, and the Hasmoneans, the High Priests, overcame and killed them, and saved Israel from their hand, and set up a king from among the Priests, and brought back kingship to Israel for more than two hundred years until the destruction of the Second Temple.

(2) When the Jews overcame their enemies and won the military battle on the 25th day of Kislev, they entered the sanctuary of the Temple and found only one flask of pure oil. That flask only contained enough oil to burn for one day but it remained lit for eight full days, until fresh olives were crushed into pure oil.

(7) It is a mitzvah to place the Chanukah lamp at the outside of the entrance to one's home, within the handbreadth that is closet to the Norway on the left side as one enters the home, so that the mezuzah will be on the right side and the Chanukah lamp on the left side. When a person lives in a second story apartment, he should place [the Chanukah lamp] in a window close to the public domain. If [a person] places a Chanukah lamp more than twenty cubits [above the ground], his actions are of no consequence, because [the lamp] does not attract attention [at that height].

(8) In a time of danger, a person may place a Chanukah lamp inside his house; even if he lit it on his table, it is sufficient.

(2) If one did not light with sunset, either due to forgetfulness or on purpose, s/he should go ahead and light until people stop passing through the marketplace, which is approximately half an hour, because then the people are passing and coming home and thus the miracle is publicized. Therefore one must place enough oil for that time, and if one put more oil in, s/he may extinguish the candle after that time has passed, and may use the light after that time.

(13) Therefore, if one has only a limited amount of money, and the mitzvot available to him are either kiddush of Shabbat or lighting the Hanukkah candles, preference should be given to buying oil for lighting the Hanukkah candles over buying wine for kiddush, since both are mitzvot instituted by the Sages. One gives preference to Hanukkah candles, as they have an additional component of recalling the miracle.

(14) Someone had a light for his house or light for chanuka, or a light for his house or for the sanctification of the day; the light for the house come first for the sake of peace in the home. For surely God is erased in order to make peace between a husband and wife. Great is the peace for all of the Torah was given in order to make peace in the world as it says; her ways are the ways of pleasantness and all her paths are that of peace.
