Why are the Lights in my Home Flickering?

This may just be the light bulb. Check that the light bulb is properly screwed in and if there is no difference, then replace the bulb. Is it still flickering? This is an indication that there is a loose wire which should be handled as soon as possible. If you can, try to not use the light until the electrician arrives as loose wires can lead to fires and/or personal injury.
