The Aux setup uses a relay, it gets a trigger input to the relay whenever high beam is selected because the trigger input is tapped into the high beam circuit. All you'd have to do is disconnect the high beam wire and tap into the low beam circuit. Then whenever the low beams are on the relay would be triggered. Then "if" you have a switch you can control it's on/off operation.


But those lens in those aren't really designed to be used with low beams as fog lights. You'd have to aim them down as to not blind other motorist at night.


That's why LR normally had em with the high beams to be used off road or out in the middle of nowhere.
