Bob, if you decide to run shielded wires to those LED lamps, ground only ONE end of the shielding to the airframe to avoid a “ground loop”. I don’t know that will resolve your noise issue, but a shielding “ground-loop” is often an issue in audio circuitry.

Shielded wire helped but didn't eliminate the problem. Turns out it was a known issue from Whelen for 14 volt systems and they sent updated bulbs which solved the problem.
