: Why do lights flicker initially when they are switched on?


Like why does it happen? And sometimes it does, sometimes it doesn’t.

Contact problems, faulty wiring connections, worn-out receptacles, or a bad filament can all cause flickering. Often, these problems occur as the light bulb ages. They could also happen as the result of wear-and-tear, improper voltage, or bad wiring inside the fixture.
