Do you have LEDS on the rear turn signals as well?
I just put put the LEDS in the tails and got the Hyper Flash...drove me nuts put the OEM bulbs back in and am sending them back to Superbrightleds.com
Is it possible if all the blinkers are replaced with LEDs that the hyper flash will stop?
I only tried the rear not the amber front?
There is a Member who installed the blinkers 3157# and does not get the Hyper Flash...his truck is a 2010...mine is a 2011
Thanks,
Fred
