Replace light bulbs with LEDs!?

[Texas Firefighter]

Do Premier and z71 models use the same tail light assemblies? Clear lens w yellow rurn signal bulb?

Yes they do. I believe all models have the same rear assembly

I use these on majority on my gm trucks. Never any problems. $10 a set and they’re bright as hell... however my newest truck is a 15. It doesn’t notify me if a reverse bulb is out so idk how it will cooperate with the 21s


License plate lights shine nicely too

I have a 2021 Premier, same rear assembly, amd was only able to find the amber turn signals that work without receiving an error. The reverse and Brake lights give an error on startup ( I have tried over 10 pair of canbus bulbs). As far as the turn signals, the bulbs are 7440 and the ones attached work excellent on my 2021 Tahoe Premier 4X4 with zero errors. I hope this helpsView attachment 271349

These worked for me as well with no errors. Just need an error free plug and play replacement for reverse lights now. thank you for sharing!

Your gonna need resistors for the reverse light. I order vled resistor for $15. You only need to put it on the left side. Just about any Led bulb will work with it. I ordered auxito for $20 from Amazon. All good now

Guy in this post said that lasfit has something that works for the reverse lights.

Tried the diode dynamic 921xpr’s and they also gave the check reverse bulb message. Too bad, because they were super bright and looked great. The company said I needed resistors, but I decided just to return the bulbs instead.

These are working so far. I had them on my 19 silverado and didnt have any issues on that truck for 2 years. View attachment 274000View attachment 274001View attachment 274002

Has anyone had success yet not getting error codes for reverse or brake lights?
