Very cool. The lights MUST be in one sideways line! That way, they cannot be mistaken for one flame, or a torch, from a distance. When they are in a line, you can see that each light is separate. So, a spiralling, or circular, line of lights is NOT a kosher menorah (hanukkiah). Put it on a large piece of tinfoil, and no drafts - that can be dangerous. If you can weld, you can make a copy of the one in the Jewish Museum in New York that has eight (actually nine) little Statues of Liberty in a row, each holding up one candle on her torch.
