The power is OUT! Flashlights dim? Candles too dangerous with kids/pets? No batteries left in the store? Try the little individual solar lights designed for outdoors. I bought some at a discount store for cheap. I keep a few on my sunny fencepost...they stay clean and within easy reach to bring inside for great indoor lighting in an emergency or any day to save electricity and use the sun's free energy.
BONUS: Our old dog needs a night light, this kept us safe & worry free.
