Glen, in stock installations all the current that goes to operate the headlights goes through the delicate headlight switch and dip switch in the cockpit.  What a relay does is isolate the headlight and dip switches from this full (high) current.  It takes just a little current (going throught the headlight and dip switches) to activate the relay, and then the relay supplies the full (high) current to the headlights.
