Magic Rear Brake Light?!? Need Help

Hi, i am a new Triumph owner (lovely scrambler 900 efi 2015) but i have an issue that i hope someone here can help with…
When putting the bike away yesterday i noticed the rear brake light stayed on. So i hit kill switch, still on, disconnected both switches, still on… only way i could get the light to extinguish was to remove the rear light connector under the seat. Any ideas? also does anyone happen to have a wiring diagram for this bike. (Digital speedo)

many thanks

 

That is exactly what happened, i would have thought parking lights would illuminate the running light rather than the brake light, i checked and switch had gone onto parking lights. Many thanks!
