The rear slide-out bed only had a center, ceiling mounted light. I added two reading lights above the headboard.
As built from the factory:
I marked the location for the new lights, then removed the headboard from the wall (it was stapled onto the wall). I mounted the light fixture bases and ran the wires on the wall.
The wires run down the center area behind the headboard, and secure onto the plywood base (pictured). The wires then run around the mattress platform and tie into the wires for the existing light fixture on the ceiling over the bed. Since this is a rear bed slide unit, there is a wire disconnect for when the slide is retracted. This is where I made the connection (not pictured).
With lights added:
