This just sounds like the 56a and 56b wires for High Beam and Low Beam were swapped. The headlight wiring didn't fundamentally change much over the years, though fog light & aux headlights did and these are for some years problematic with some LED bulbs.

The high beam indicator can have issues: if the LED bulbs drive both high & low concurrently for high beam or if low beams stay high impedance when they are off. In your case it doesn't sound like either of these.

Alan,
The thing is they operate fine with the OEM type bulbs save for the the strange headlights cutting out at 3500 rpm which I believe I've traced to the CE panel since the relay is brand new.

It's possible the led bulbs have the low beam and high beam contacts reversed. Since I didn't have a connector to plug in, I treated them as 3 single wires and using a meter and test probes just figured out which was the common ground (middle), which powered the low beam and which powered the high beam and hooked them up to the proper terminals. If you have one side correct and the other incorrect is when you'll get the glowing (but not illuminated) high beam dash indicator, even on low beam.

 

That's exactly what I was thinking - seems it must be that.
