Someone dropped something on my K75S when it was covered and when I uncovered the bike I found that the right rear turn signal was broken off. What parts do I need to replace the turn signal? I am not really knowledgeable, so I really couldn't tell by looking at it whether the entire plastic assembly (holding both turn signals) that goes under the seat has to be replaced or if just the small arm that holds the right-hand light can simply be changed out. The signal itself still works so the wiring appears to be fine. Any assistance with part numbers and possible sources of supply would be appreciated.
