Random lights and I cannnot use the decorations box to remove them (apartment issue).

Can you edit that part in build mode? If not, then I think the decorations box will not work for them. The lights probably appeared as part of the communal decorations for that apartment block, just like they appear on neighbours houses.

That’s helpful to know, but potentially annoying. Thanks @elanorbreton. I will investigate.

UPDATE: You’re right @elanorbreton. That is the very limit of the apartment so there is only so much access. It’s worth noting that when you buy a decorations box it won’t let you choose decorations at all, it simply blanks out with “Not Allowed in Apartments.” :/
At least the silly box more than paid for itself via Rummage for Decorations. >:)

Anyone know of a workaround?

That happened to me too when I was living in an apartment. You have to create a new holiday on the calendar for the next day and set the decoration theme to "none". Then the decorations will go away. There's also a bug report about it here: https://answers.ea.com/t5/Bug-Reports/OPEN-CL-S-Unable-to-remove-holiday-decorations/td-p/6909543

Thanks @Evie0602. I did “Me Too”.
