I live in Arizona. I took my last truck to California and I got pulled over twice. while I was there for the week. Maybe it's because of out-of-state plates, but I had 4 KC lights on a light bar and they were visible (NOT TURNED ON) - and both told me you can only have 4 white forward-facing lights. So, with your headlights and fog lights, you have 8, those need covers. I said, I don't have covers and it's not even night time and I don't use them for any on-road applications. Hate that state.
I am getting old. I just like lights.
