Update: Ordered better bulbs from Amazon and received them today and installed on rear with no hyper-flash. Installed on front and then had hyper-flash. So for now I am running full LEDs on the rear and regular bulbs in the front. Not sure I want to install the resistors on the front because of the heat. NOTE: Strange thing is the emergency flashers have no hyper-flash, just the turn signal when running LEDs on front and ear. I bought some cheap 7440 LED bulbs ( 7440 LED Bulb - 15 LED Forward Firing Cluster - Wedge Retrofit | Wedge Bulbs | Specialty & Automotive | Universal LED Bulb Finder | Super Bright LEDs ) to test in the 2015 tail light. The bulbs fit fine and there is no hyper-flash or dash board errors. I will now order better bulbs for the back and new 7443s for the front.
