I’m still working out how the house “works”, such as whether any elements are steam-powered and/or require electricity. The idea behind the lights is that they’d indicate the level of charge on the “charging station” inside the house.

The house is a heavily re-modelled and custom-textured version of the Fairy Mechanic’s House by 1971s. The “charging station” inside is my custom modification of 1971s’ Steampunk Area B set. The rest of what you see in the render is in Sara’s bedroom.
