That is unfortunate. I guess cause they are heritage items. I assume they can go in the bank but another alternative is to put them directly into the new deco pallete. Will clutter it up a bit but better than taking up a bank slot. (counts as a deco in your home but if put directly into the pallette the item can be hidden. Edit: I wonder if they would count as lights in your home then, probably so not as great an alternative as I was thinking.
They are very modern looking lights. Was hoping to see candles with colored glass connected by garland, but I guess that is a lot fancier.
