I think there were four options when I was messing with it in forscan: low beams always on, turn signals as DRL, fogs as DRL, and accent lights only. Or something to that effect. I have a Canadian car so factory settings were low beams always on and that bugged me. Didn’t enable the cluster option to switch them on and off. Decided I liked the turn signals as DRL for a different look.my DRL are set to off now in my settings menu on the gauge panel, but when they were enabled, my fog lights are the DRL with stock turn signal lamps.
