headlamp

Hi mate contact triumph as there was a factory recall on headlight units. I know this because I recently bought a 2012 street triple with the same issue and contacted the dealer who replaced it free of charge. Hope this is also for your bike. Save you a pretty penny.

 

The recall was only the hexagonal lights used on the Speed and Street Triple, I had the lenses replaced on my 2011 Speed Triple twice without any issues.
Never heard about any issues with the Bonnie's
