Go it to work the day time running lights TRUN OFF when the HI BEAMS are on . Turned hi beams off daylight part of fog light goes on . NEVER would have guessed that .

Why not run with the High Beams and Fog lights on all the time? The only time I use the Low Beam is at night when a vehical is approaching me. I'm running HIDs for all 4 lights.

I had the EXACT same incident a couple weeks ago. The vendor wasn't aware of the correct function, but the MFR was. MFR explained it's a DOT thing..
