Light bar interferes with CB radio?
I have a 50” curved light bar wired to an on/off switch. I recently installed a CB radio that works fine until you turn on the light bar. As soon as I turn on the light bar, there’s an awful, loud, patchy static noise that comes through the radio. I think the light bar must be interfering with the antenna somehow. It’s kind of annoying because I can’t use them both at the same time. I’ve recently noticed it actually interferes with the OEM stereo in the same way when I’m listening to an FM station. I don’t really know how to go about fixing this, if I even can. Could someone help me out? Thanks.

I would assume you don't have a strong ground for the lightbar or it's possible that the light bar is throwing out some EMI.
Is your CB antenna wire isolated from any power wires (if you run a power wire next to the CB Antenna wire, you will get interference)

I was actually considering using some ferrite chokes, like the ones on laptop charger cords. They’re supposed to suppress electromagnetic noise I guess
