I also did the dl8 to dl3 mirror upgrade recently, I'm sure you're aware of but, everything works fine with the original turn signal bulbs in so I don't think the new signals in the mirrors could be causing any trouble?

ok ill try that.

Yeah more info there would have helped. I have replaced the entire tail light assemblies with Spyder LEDs that must have the resistors built in. They were installed about 6 months ago and I've never had a problem with them. Also installed a Putco 48" Blade taillight bar under the gate and have never had a problem. I got a set of Spyder DRL projector headlights and bought a set of amber LED turn signal bulbs. It wasn't until I installed the turn signal bulbs that it started hyper flashing and displaying error message "turn signal failure" "side note"; It only happens when I fully engage the signal. if I just hit the quick signal, 3 flashes only, it doesn't fail. I've learned about how LEDs register lower ohms so the truck thinks there are no bulbs, makes sense. The ECM runs the signal relay so there is nothing there to replace. So I bought 4 LED load resistors specifically for the hyper flashing and error message. "See Pics" The resistors were not plug and play on the socket side so I used the sockets that were on the lights and wired 2 of them inline on the passenger side. One for each bulb. Bulbs work but, still have hyper flashing and error message. To test, I fully engaged the signal handle, I didn't use the hazards. Note that if I put back in the original bulbs, everything works fine and the original bulbs are installed on the driver during testing. The only thing I can think is I've got a bad set of No Name resistors..

I just changed all lights on my 2015 Silverado to LED. I didn't run into hyper flashing and error message until I changed the front turn signal bulbs. I purchased resistors for each bulb and wired them in on one side so far and still get the error message and hyper flashing? I shouldn't have to do the other side for one side to work right? I don't want to cut the other side if it's just not going to work. Has anyone got this to work and how please? Thanks for any input
