I have had persistent problems with cracking indicator stems on my 2010 Speed Triple.
It seems that several 2012-2013 Triumph triple models have been recalled to rectify the same problem:

Here is a post with a picture of the most frequent problem which I have experienced 3 times, though I have also had one indicator break on the main stem:

Has else here experienced this problem?
Has anyone support from the local Triumph distributor?
Additional Notes:
If you get a replacement indicator lamp assembly from Triumph it will have the indicator lamp, the stem, and the wire lead. The wire lead needs to be attached to the electrical system in an inaccessible location necessitating removing the tank etc. Fortunately, the indicator can easily be replaced by removing the lens and then detaching the wires at spade connectors within the lamp itself.
On other forums it has been noted that the Aprilia Tuono has the same indicators. I am not sure about the Tuono but it appears to me that Aprilia RS models (125 and up) have an identical indicator lamp assembly but slightly different stems. These might work as a superior replacement though I am not sure how the price compares to the original Triumph part.
