The circuitry over the sink was wired in such a way that either a switch would control not just the sink light, but the Keurig and carport light (um, not happening), or the sink light would be on all the time. At least I can get around that with a smart bulb. Since smart bulbs aren't as stylish as the decorative ones out there, I picked an opaque sconce that would hide it.
As with the strips of under cabinet LED lights (installed when I changed my kitchen colors), the switch for this smart bulb is a Lutron Pico remote that sits right on top of the drywall.
