Aux switch causing static in radio

[Jbird]

Just wired a light bar to my #1 upfitter switch. I noticed last night its causing a lot of static in my radio signal when its turned on. Only thing i could think has anything to do with it is im grounded to the fog light ground wire. Think this could be it? Anyone had any problems like this?

My power outlet does that when it has a 12v usb phone charger in it. Sounds like a little static through the speakers in my case. Or are you talking about something different?

Sounds like a bad ground
