We have them as well on the 3rd floor. Funny enough, for whatever reason, my father hates them and his way is to use the very small flashlight I gave him if he wakes up in the night. He's 91, and set in his ways.
That said, if I'm going to spend that kind of money on a toilet seat, kind of stupid not to use that feature isn't it? Personally, I like it. Light doesn't come on until you hit the bathroom area, and instead of giving you dimming light around the toilet, it gives you light IN the toilet so if your standing, less chance of missing your target because the target is lighted LOL, particularly for my dad whose aim isn't what it once was
