I have recently installed LED flood lamps on my 2001 Ford E-250 RB50.
I have noticed when the LED flood lamps are on, the
radio has high white noise.
And at times, I have noticed when a phone is connected to a
USB charger, making a phone call, or listening to listening to audio (YouTube, Pandora),
white noise is heard here as well.
For the
USB Charger, a simple solution has a Ferret Core:
RAVPower RP-VC006 Red USB Car Charger
And place a
ferret core near the LED flood power:
Ferrite Core Bead Choke Ring Cord RFI EMI Noise Suppressor
Thoughts?
