We are commanded to light Channukah candles at night, to usher in each day of the holiday, and, if my memory serves me, we may light as long as there are people outside who can see the candles (ad shetichleh regel min hashuk). If one is lighting for others to see, one is performing a pirsumei nisa, publicizing the miracle.
The next day, though, is still that day of Channukah, and people will, no doubt, be around again after a good night's sleep. Why can't I light in the morning, when I can be sure people will see it?
I am not asking about the practice of lighting in shuls in the morning (as per this answer), but about doing it with a bracha to fulfill my personal requirement if, for example, I was not able to light at night.
Unlike Shabbat candles which I can't light in the day time, I am allowed to kindle the flame. So why can't I complete the requirement with the blessings during the day time?
