So I installed two A pillar LED lights on my '19 JLUR and wired them to the factory installed AUX switch 3. Everything works fine with the lights, but If I have the radio (8.4 inch) on, I hear static coming from the speakers as soon as I turn the lights on, and it goes away when I turn them off. Any ideas on what could this be?

Putting ferrite chokes on the wires might help.

Did you ground to the chassis or to negative post of the batteries? Might be better directly to batteries.
I did it to the chassis, specifically to the bolt they provide you with to ground, right next to the switch wires

Did you run the wires into the cabin in the passenger's side door well? There are wires for the aux switches right by the battery...

Installed two sets. Spot and flood lights. Wired them into my own diy switch panel. Flood light switch is okay but spot light switch causes so much static that I can't hear anything from the radio. Just wondering if there's a fix for it.

Try some better lights. Some LED's give off Radio Frequency Interference. Usually your better ones are ok.
