Hi Dave, the dealer is talking bo**ocks. Just fit and splice into the brake light wiring. My bike has more led`s than you can shake a stick at fitted at the back. 48 extra in high level brake lamp, 24 as extra running light on bottom of number plate. Also the led`s in the lamp unit I replaced. As the led`s hardly ever blow, (never had one go yet), there is no worry on my part at the rear so to say. Ditch the bulb in the tail light as well to make it safer.
No problems in 6 months use with the can bus system. Just one insignificant word of caution, the can bus detects a no current flow i.e. when the filament of the bulb blows when the circuit is operated, and shows a warning symbol on the display. As there are no filaments to go this will only show a fault if the wiring is broken. I tested the system after fitting it by disconnecting the units wiring and it showed a fault on the display. But if you have one led go theres lots more left operating. This would only apply to your brake light circuit which if the bulb filament went would not show a fault as you would still have current draw on the led`s
