“ As a result, if there is at least one man, woman, boy or girl who is of age to have understanding, blessings can be recited since there is publicity. Even if these people have already lit a Menorah for themselves they still serve for publicity's sake. ”

“ Section 2 From his language it is clear that if one lit after sunset, he need not use a quantity of oil sufficient for half an hour, rather only enough to last until the marketplace empties of people. ”

“ If so, nowadays all would agree that it would be permitted. Even so, some caution not to pronounce the blessing if the candles are lit after halachic midnight (Magen Avraham, comment 6, in the name of the RaShal) . It does not appear that this caution is necessary, and as long as household members are awake one may recite the blessings. If, however, they are sleeping on should not recite the blessings (see there) , since it does not remind any other person of the miracle, and publicity is required for at least one onlooker besides the one who lights. ”
