As written in the last post, I used the Unswitchable Switch converted by Simsinlowspace to make a functional switch that can be used by your sims to turn on/off the room lights. They won't turn on/off immediately like the usual functional switches do, but the choosen sim will go in front of it to actually press the switch and it will move up or down as you can see here:
The switch is shiftable but I also added a second version if you don't have Apartment Life EP (choose one). It won't disappear when walls are invisible. It has a new Guid so you can have both the deco version and mine in your game.
Hope you like it.
Found in Buy Mode-Lighting-Miscellaneous for 5 simoleon.
