I'm completing a week of mods to my new(to me) NC.
Stebel horn install with relay and harness, also added Honda aux harness and relay/fuse.
Lastly installed a USB port in the frunk, and I'm completing the wiring for a set of aux lights.

Here's the thing. These lights have two wires. One is for the halo outer ring, and I wired these to the switched ignition for DRLs.
Granted our headlights in the US never go off completely, but I wanted to wire the second wire to the headlights, which then controls a switch.
On once, low, on again, high, on again, flashing.

So my problem:
If I wire to the low beam, they won't work on high.
I I wire to high beam, they won't work on low.
If I wire to the running lights, they will go off when turn signal is on.
If I just combine the two wires to switched ignition, I guess that will do what I want.

I guess what I am asking is - is there a wire that is always hot when lights (low or high) is on? In a car it would be the parking light circuit.
 
Wire to the ignition. Lights go on when the bike goes on. Off when the bike is turned off. Just like the headlamp.
 
There are some spot lights produced in China that perform like yours and can only work as normal lights with a modification to the light itself. I have a set I couldn’t use as mine couldn’t be modified.
 
Not a direct answer, but have you checked out products like the Skene IQ 275-A controller?
I have it run through a 3-position switch (not necessary) and they also work in conjunction with the brights.
They have no power without ignition, but once I turn the key I have 4 options.
With the 3-position switch I can choose to turn them off, 50%, 70%, or turn on the brights and the auxillary will light up to 100%.
I ride with them at 50% at night, 70% during the day, and hit the brights on the last 15 minute stretch of darkness before my home.
You can easily custom program the percentages as well.

Mine are Denali LED DRL lights and have hi/lo functionality. Originally I set them to function High when headlight was on High. Low when headlight was on Low.

Then I tried High when headlight was on Low. Low when headlight was high.

Settled on HIGH 100% of the time because the light are wide dispersal and non-blinding since they are conspicuancy lights that are not really designed to light the road.
I installed them to be seen by oncoming drivers. For that purpose they work well.

+1 on the Skene controller. It is a very useful device for controlling auxiliary lights.

Triggering the lights to 100% bright automatically when the high beam is on works great on older NC models, but I hear on the new models with LED headlight, it’s trickier to get a useful high beam signal.

You're right, now that you said it I do remember reading that at a certain point Things did become trickier. I ride a 2015 for what it's worth, I am not sure of when the changeover took place, 2016?

Doesn't seem to be an issue on a 2018
 
2018+ with the LED lights have 5v signal on the aux harness high beam wire, vs 12v on the older ones.
For now, I wired to the ignition, so I have the outer halo light on constantly, then I can turn the switch on (1-3 clicks) for low, high or flashing. Works for me.
 
It's not all that difficult to install dimmable auxiliary lighting to the newer NC750's but it's not perfectly straightforward so requires a little additional work. I put together a long-ish series of posts on how to do this here: https://www.nc700-forum.com/threads/auxiliary-lighting-for-2018-nc750x.16641/

There's wiring diagrams there along with required components and sources that'll allow you to put together a system that will switch aux lighting from full to dimmed in sync with the headlight hi/low. And the level of dimming is adjustable too ... all for under $40 (but ya gotta assemble it yourself).
