Correction, the low beams do NOT turn off when high beams are turned on. So if you are going to use the high beams and have the fog light relay tied into the low beams. Then you will have three sets of lights on fog, low and high.I would love to, yes they will turn off when you use the high beams(they do whatever the lows do). It's nice because it doesn't turn on the green fog light indicator on your dash (so you don't have a cluttered instrument cluster). when you turn the fog switch on the green indicator light turns on but doesn't turn the fogs on or off(disabled). I will do i detailed right up tomorrow or the next day with pictures.
