Don’t use candles
While lighting candles when the lights go out seems like a classic solution, this isn’t really your safest option. Kids or pets can easily knock them down, and you should never leave a burning candle unattended when you go from room to room. You even have to be careful of some candle holders, which can become very hot if you leave a candle burning for too long. Instead, stash flashlights in strategic areas around the house, and check them periodically to make sure the batteries still work.
