LED tail light issues

I have an 05 F250, I’ve added a ranchhand bumper and headache rack with al LED lighting, and for some reason after adding the replacement led bulbs to the factory taillights I now get feedback whenever I turn on the emergency flashers. It will actually flash the dash lights inside. But that’s not all, it messes with my trailer lights as well. Turn on the left turn and the markers and the entire trailer flashes (and the grounds have been checked.) swapping back to an incandescent fixes the issue but I’d rather have the led.

anyone have an idea I might try? Resistors aren’t helping either.

Yes, sorry I forgot that detail. It is a heavy duty electronic.

Is Heavy Duty Electronic the correct flasher? When you put Led in you are lessening the load. I put replacement led bulbs in my tail lights and front turn signals. The only thing I needed was a standard load flasher that was led compatible. I pull a a couple of different trailers and they all work fine. (2006 f250).

I used the EP27 electronic replacement for our trucks and rated for all led or a mix.
