As part of a kitchen renovation, the designer would like us to install sconce lights above the window over the sink. This is a load bearing exterior wall and there is a solid header across the top of the window, so I'm just not sure how to get the wires to the sconces.
I realize I can mount pancake boxes, but I'd have to cut a groove or something in the header to run the wires.
Any ideas for how I could safely wire up these sconces?
