When I was driving to work this morning, my headlights were on, but the bowtie wasn't (at least not that I could see reflected in vehicles in front of me). If I turn the automatic light control off and flip it over to DRLs or Headlights, it does come on. Unfortunately, I can't see the front of my truck while driving so I have to rely on reflections off other vehicles, but I figured it would at least be bright enough to see in a reflection.
