With Kohler nightlight technology, you can safely locate your toilet in the dark without turning on the light. This Reveal toilet seat offers a choice of two brightness levels so you can adjust the lighting as you, please. An LED guide light on a 7-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 soft-close seat also features innovative technology that prevents the seat from slamming and simplifies both cleaning and installation.
