I bought a set of turn signals from procycle for my 06 XR650l, and when I installed them they didn't flash. I switched the wires around several different ways, but still can't get them to blink. The kit I ordered is #5 in this link http://www.procycle.us/main/dskit.htm. Do I need to purchase the turn signal flasher (item #8) to make these work? Or am I just retarded.
