I use the power from the dimmer switch to power the relay, and then have a direct feed from the battery to power the headlights, which is switched by the relay. I used circuit breakers for circuit protection for the power feed to the headlights. The power to control the relays is protected by the headlight switch breaker, and the power feeds to the headlights are protected by individual breakers. My setup anyway...
