On Chanukah, our Rabbis, Hillel and Shammai, have written about different ways to light the menorah. Most people light 1 menorah according to Hillel, but some people light 2 menorahs: one according to Hillel and the other according to Shammai. I want to know which one should be on the right, Hillel's or Shammai's? Please be specific as to whether looking out from inside, or in from outside. Thank you.
