I have all led lights on my truck. I have amber led turn signals, spyder taillights, and a 60" tailgate bar. It never used to hyperflash but it suddenly started and I can't figure out why. Please help.

The LED bulbs are notorious for this. You can try disabling the Hyperflash with the Forscan program, take it to the dealer to disable, or tie some resistors in parallel to increase the load on the circuit.

See I thought about the resistors but all of my lights, even my headlights have preinstalled resisitors except for my tailgate bar but it's plugged into the 4-pin

Maybe a resistor went up. Check them with a mutimeter. Should read 6 OHMs.
These trucks are sensitive when it comes to the turn signal hyperflash, too little current and it hyperflashes, too much current and the BCM will kill the turn signals until you reset the fault. Too many resets and you will need a new BCM.

What do I do if that happens

M3TOSVT

If you are getting the Hyperflash and the light is still flashing, you are on the low current end. If your turn signals stop working all together then the BCM has shut down that circuit for an overcurrent condition. It will need to be reset with the Forscan app or dealer tool.

Or you could have a burnt out bulb somewhere.. usually on the side that is hyper flashing.

They're all leds. But regardless they are all on and functioning. Just the whole right side is hyperflashing

Electronic LED Flasher EP26.. we use this in 04-08.. I assume it may work for newer models too

Don't think these work on the newer ones. Everything is controlled via BCM. You will have to give the BCM what it wants. Usually 2A for turn signals if I recall correctly.
