This jumbo alarm clock features a soft silicone case and a large digital display which lights up at the touch of a button. It is just as easily viewed at night as it has Smartlite® technology, where a bright, green backlight illuminates the display as the room gets darker and turns it off again during the daytime to prolong the battery life.
