There is a white LED rope light that goes under the granite counter edge...
Thanks, that got me started. There's NOT a rope light under our granite, but that got me searching further... and it looks like there's a rope light just underneath the upper wood "medicine" (storage) cabinet. Now that I see that, I also see #20 -- 110V "flex" light -- in the Parts Manual. Not working, of course. At least I'll know now what the heck I'm missing.
