I took a search on the internet, and it turns out that the active suspension system on the H2 and Versys 1000 use a system developed in Australia, that samples and reacts 500 times faster than any competitor...... that sort of data rate is indicative of a CANBUS system.
Wikipedia has some info on that.
The most important takeaway being that CANBUS uses the power bus for reference. The operating parameter that is most important would be that it operates 0.9 volts below the positive value, and has to have a difference of at least 3.5 volts to operate..... in simple terms on a 12VDC system, it would have a high signal of 11.1, and would need the low side to be no more than 7.6 volts.
If the 'high' side is 'pulled' lower than desired, say to 8 or 9 volts, then the system is unlikely to communicate.
LED replacement lights can easily cause issues with this.
A current limiting resistor would reduce the opportunity for the aftermarket gizmo to upset the CANBUS.
The trick with that, is to put the resistor AFTER the device. +, Device, resistor, -.
If you know how much current the gizmo actually needs, you can make it difficult for that circuit to draw more current than it needs (which has the potential to lower the bus voltage). LED bulbs use very, very little current. 12V, LED, resistor, -. If the resistance is great enough, not very much current can flow. 12/ 100 ohms, would allow a maximum of 0.12 amps to flow. That's 120 milliamps, which is almost certainly adequate for any marker bulb, accessory type of device. As the '19 already has LED headlights that are compatible with the bike, someone has to have already done the math to work out what is correct for that.
The aftermarket almost certainly has not.
