Hello, I recently bought a set of nilight ditch lights and a light bar for my 100 series, they work great and the wiring harness it came with seems good so far. But they came wired to 1 switch, and sometimes having all 3 lights on at the same time is way too bright so i was wondering if there is any way to wire in another switch so i can turn on my light bar separately from my ditch lights. i already have extra switches. thanks
