This is a replica of a car problem I've had recently, all related to CANBUS.
The car problem was when towing my caravan (so excuse the long explanation). So new caravan, towbar fitted with vehicle specific wiring harness and car reprogrammed to recognise the towing module in the harness. Twin reversing lights and rear fog lights on caravan not working. The issue is that these are incandescent bulbs, and the current draw of the pairs of lights was over what the towing module was expecting and so it shut those lights down. The harness manufacturer had programmed the module for single reversing and fog lights, and they sent me a set of appropriately ballasted LED bulbs to get it all to work. QED!
So, with a CANBUS vehicle with LED lights, you won't be able to replace the LED's with incandescent bulbs (and to some extent why would you?) because circuits aren't designed for the increased current and need protecting...
When considering electrical stuff on these bikes you need to get out of the traditional 12v (or even 6v!) wiring mindset...
