On the comment about radio interference when the LED headlights were on is similar to an issue I am seeing after adding some LED floodlamps to my rig. All the lamps are run with Relays and common ground, and the radio is on it's own power feed but uses the same grounding point. When I turn on 1 LED, I hear a slight static. If I turn on my LED lightbar and rocklights, the static is so bad I can no longer hear the station on the radio. Switching them off again stops the static.
What's the best course of action? Do I run new power and ground directly to the radio, or is there some Diode that I need to install on the LED circuits? TIA
