Noise interference from LED mood lighting

[Franz Gerschwiler]

Getting some interference when the mood lighting is switching on. It's a high pitched hum in nature. Dealership installed a JL amp and SUB before delivery so I can't compare with factory. Anyone else have these issues?

I just posted on another string. It's a ground issue w/head unit or the lights. May have to run a good ground to battery.
