One final tip here, the original design of the flasher works on resistance in the circuit. If there is zero resistance, then the flasher doesn't do it's typical "boing-click" sound and no flashing happens. We will all inevitably run into this as we upgrade to LED lights all around the vehicles. I bought what is called a "Zero Load" 2 prong flasher from for about $10.00 shipped to my home.

Its kind of annoying because I can't hear it make a sound and sometimes, I forget to cancel the turn signal.

Food for thought.
