Default Installed Switchback LEDs Not Working
I have installed the hyper-flash harness and switchback LED's and my turn signals are not working. Parking and driving light is fine.

No turn signals work? That would be a bad hyperflash harness.

Have you tried installing again the OEM bulbs with the hyperflash harness in place to eliminate the possibility that the flasher in the hyperflash harness is malfunctioning?

EDIT: I just missed the previous posts while I was typing

The original bulbs work fine. Thinking about just picking up some amber LEDs to see if they work instead of the switchbacks.

It would be good to test them with the hyperflash harness to verify for sure that the harness is fine

Got it working. Needed bulb grease as they would not seat all the way into the socket.

What bulbs did you use? I ordered some flashbacks a while back and never could get them to work. Went back to OEM.
