Some have the EVIC that tells them when a bulb is burnt out, I think this is on the 2013's, maybe even on the 2012's
Evic, may be wrong on the 2012's I don't have Evic on my 2012. If you replace your flashers with LED's they will also flash hyper fast, this is the truck indicating you have a burnt bulb, basically the Relay does not sense a load, does the same with the LED bulbs because they have very little resistance and draw very little power to light, by adding a resistor to the body from the positive of the bulb you create a load as if a regular incandescent light is there. Canbus LED bulbs have a built in resistor to create the load so the Evic does not give an error, for Flasher bulbs not all canbus LED bulbs will work for the hyper flash, but will silence the Evic.
