With Kohler® Nightlight technology, you can safely locate your toilet in the dark without turning on the light. This Transitions toilet seat includes an LED guide light on a 7 hr cycle to help you see your toilet in the dark, as well as LED lighting that illuminates the bowl when the lid is lifted. Made of durable stain-resistant plastic, it includes unique Grip-Tight bumpers that keep the seat from sliding out of place.
