Okay, just locate the power feed wire to each low-beam headlamp bulb, right behind the headlamp assemblies, and cut your rocker switch wiring into that. You will need to run wires from the headlamp harness up to the dash to your rocker switch, and back again. There'* no other _easy_ way to kill _only_ the headlamps _only_ when you want to.
You want this wiring and switch to be dead-reliable since those are the headlamps you're relying on to see by at night, so solder your connections and make sure you use the proper gauge of wiring (at least a 14-gauge stranded; I would recommend 12).
Your headlamp-out warning will probably go off everytime you cut them with your rocker switch, but I assume you don't have a problem with that.
