Terry the Tiger Portable Night Light sheds a soft glow to ease fear of the dark and is an entertaining companion any time of day. Terry is operated using a single, easy to press button on the bottom. Your toddler can select his or her favorite night light color (yellow, teal, orange, blue or pink) or press and hold to enter soothing rainbow color change mode. In this mode all five colors fade in and out in sequence creating a fun, rainbow effect. Terry the Tiger runs for over 100 hours on three, ordinary AA type batteries (there are no sealed rechargeable cells to wear out). With the handy 30 minute auto off feature Terry will operate for over six months between battery changes.
