Two weeks before my EU tour but!
On my 2019 114" Limited I changed out and installed LED's in indicators (work OK) and rear light plus, attached saddlebag (stuck on) and filler inserts. Once the Can Bus system recognised it; all was well.
Now discovered one Infill not working and brake light not coming on. All running lights for LED's are OK. Just that pressing either front or rear brake, not coming on.
Removed additional rear added connections, installed standard bulb rear light and still the same. Running light OK but no brake light.

Two weeks to sort it out. Any suggestions?

Once you start adding aftermarket, probably made in China LED it could be anything… poor earth, resistance with the LED etc… time to find a local auto electrician to line test, connector to connector.
 
So, what was wrong?
 
Out of interest what make are your aftermarket lights ?
 
I fitted a 1" ball clamped to the existing brake lever. Adjusted both the lever & handlebar control console to an angle I prefer.
What I did not notice is that from the front view, there is a notch into which both parts need to lock into. Mine was not. To the left of that notch is the brake sensor switch in the switch console housing.
Therefore my lever ended up too far to the right and was not hitting the switch when pulling brakes.
My red security light was always on as well but, thought it might be low battery.
Once I was shown my mistake, a quick job with my tool roll bit and job done as shown back in the slot.

How does that explain the rear brake not activating the stop light?
 
The brake sensor is part of the handlebar switch cluster. Activated when brake lever pulled to send a signal to ECU. Lever is physically separate from switch.
Because I moved both to get an orientation I preferred, they were not touching. Therefore, it did not send a signal to rear light via ECU.
The 2nd photo shows correct positions for both to be in. That notch is a guide to give correct distance.
