With KOHLER Nightlight technology, you can safely locate your toilet in the dark without turning on the light. This Transitions toilet seat offers a choice of three brightness levels so you can adjust the nightlight as you please. An LED guide light on a 10-hour cycle helps you see your toilet in the dark, and LED lighting illuminates the bowl when the lid is lifted. Unique Grip-Tight bumpers hold the seat firmly in place and prevent shifting. This seat mounts easily from the top of the bowl using only a screwdriver, thus eliminating the need to reach under the bowl to tighten. Quiet-Close technology prevents the seat from slamming, and a ReadyLatch hinge makes seat removal easy for cleaning.
