Hyper flashing

[PriceMA2001]

I've got a 2022 trail boss with 5.3- and recently purchased ANZO led taillights. I've installed them and I like them, but they hyperflash while using turn signals and send a code to check taillights. Hazard lights work properly (No hyper flash)
I've ordered a replacement but problem still persists.
Is this common? Are there other LED lights that will work for front and rear?
I've de-badged, installed black lug nuts, and I'm looking to keep the tinted LED if possible.

I remember when I installed LED tail lights on my old Suburban I needed to splice in a resistor so they didn't hyperflash.
I know Anzo sells 2 different sets for the TB. One for the LED tail light equipped TB (LT) and one for the non LED
equipped. (custom). They use different resistors. Contact Anzo. They can probably help you out.

Are they for OEM LED tail light replacements? Regular Silverados have halogen bulbs and have resistors in the aftermarket lights so they don't hyper flash. Make sure they are also installed in the correct polarity.

I've been using Lasfit LED bulbs in my front turn signals for a few years now. No issues.

My truck came with LED tail lights, but had an incandescent white bulb for the reverse lights. I changed all my lights (headlights, turn signals, and marker) in the front to LED. I also changed the reverse lights and license plate lights to LED.

I had hyper flash on only the right (passenger) rear tail light. I had the dealer check and they said it was because of the LED lightbulb (that I put in) in the reverse socket that caused the hyper flashing. I told them that they did not know how electricity works since the lights were not on when the hyper flashing was occurring. I told them to check for loose connectors, and possible floating grounds. The changed the tail light assembly twice. After the second time I checked all the connectors and found a few that were loose and not locked (red clamp closed). I fixed that and have not had any problems since.

From my experience with the dealership service center where I purchased my vehicle from, I believe they are good parts exchangers but not good mechanics/technicians. I know some call themselves auto technicians because they work on electronics and computer system of the vehicles. Others don’t mind being called auto mechanics and they do check computers and the electrical system.

I have gone to another dealership and will continue to go to this dealership as they did right by me. I needed the turbo to be replaced as it failed, and they paid for the rental since they did not have a loaner vehicle. They had my truck for a little over a month.

MedicJim, what year is your truck? I have a 22 refresh LT and my passenger side front headlight assembly was faulty. It would hyperflash randomly before and after I added reverse light and license plate light leds. Dealer put a new headlight assembly in under warranty and the issue was resolved. Glad I caught it under warranty b/c the assembly is around $1500.

Did you ever get this fixed or find any resolution? Same issue 2019 Trailboss.

Buy quality, name brand LEDs that have the anti-flicker.

I was referring to aftermarket light assemblies and not bulbs. My truck was LED to begin with but wanted a different style. Thanks
