Landing Light Hum

[TheFrisco]

I have a him on my SL30 radio when I turn on my LED landing light. Yes I changed the capacitor, even upgraded to the larger Red bull can size one, still a hum.

Any suggestions what else it could be? Could the landing light not be wired thru the capacitor?

Thanks TheFrisco

PS: getting slowly but surely really comfortable flying my CTLS named "Theodore" in Maui winds, today it was 20 gusting 29 with a 20-30 degree cross and I did well ... So happy with Theodore
