if so how
Yes. Mount the relays (one for lows one for highs) up front near the battery. Use a 30 amp breaker to power the load inputs to the relays. The load output from the relays hook to the wire that was hot going to the headlights. Ground the relay coils to a good ground under hood. The wires that were hot from the switch now triggers the relays.
