Lightbulb tweak, let’s see if any lightbulbs go off.

Unscrew all light bulbs in the house and put them in the freezer for 48 hours. Remove them and immediately put them in the warmer main section of the fridge for 6 hours to let them thaw slowly. Remove and screw them back into sockets. Also put all new unused light bulbs in freezer along with the others. You can do this light bulb tweak in stages so you can have light when it's dark outside.
