Part of the inspiration was also because the rear signal lights ground out through those stems,and without them and that ground, well, you obviously have no rear turn signals. But I wasn't prepared to pay $110 for them.
All I did was take the front stems and drill them out to 12mm (that "10mm" mark is the size of the original hole).

(That white light on the left signal is from my headlamp - I forgot I had it on...).
