During regular use, this innovative LED night light emits a soft, white glow. During a power outage, it promptly comes on and can be used as a portable flashlight – just remove it from the wall and you are ready for any emergency. The night light includes a light sensor, which turns it on at dusk and off at dawn. The rechargeable battery (which is nonreplicable) charges while the light is plugged into an available outlet. It also features a foldup plug for easy storage when not in use.
