I have a set of driving lights that I turn on and off with a switch right now, but I'd like to put a relay on them so they turn off when the brights come on.

Does anyone know if it'd be possible to hook up a relay to the wire going to the lights and send a wire from that to the bright wire so it opens when the brights are on?
I really still want to be able to control them from the switch besides automatically turning off when I put on brights..
