A resistor in my LED tails went out and I was getting hyperflash on the right blinker. If you install Switchback turn signals this will cure the hyperflash as well. Got to Napa/Carquest/vatozone and buy relay EP-27L ( the L is for LED) Take off the cover underneath the steering wheel. (7mmx2) Take off metal plate (8mmx4) Find the relay on the left side with the blue plug. If unsure, turn on hazards and listen to it clicking. Replace with new EP-27L. No more Hyperflash! Best part is the other side still blinks normally.
