Mexican lighting

My brother brought me back a bunch of sconces from Mexico this month. They have no wiring, but the cases are cool. So now I need to wire them for actual lights, something better done in the states anyway. He brought them home on the plane, and sent them to me from Santa Fe. Gotta love the rels, they really take care of me. To be clear, this picture shows the shop where he bought them, not the ones he bought.
