No idea. I'd double check which bulbs pertain to the brakes and turn signals then go from there. Even tho it doesn't have hyper flash, the resistor still might be wired wrong, or maybe even on the wrong bulb. Idk, I'm just guessing. Gotta start from somewhere. If you still have your stock lights, maybe put them back on and go for a right and see if the cruise works. If not it could be something other then those lights. Something to consider....

Cruise control worked perfectly with the other tails that came off and those were LED as well. So I know it’s not a problem on the truck side. As far as I can tell the pigtails are plugged in correctly as all lights function as they should. When I had the original set of this style that had the condensation in them, I had swapped the plugs by mistake, and the led tube was flashing as a turn signal and the turn signal blocks were not on. Switched the pigtails and they functioned correctly. So I know that’s not the issue either. Maybe I should order different resistors and wire them in?

I think it may be your brake switch, it's the sensor connected to your brake pedal. I know when they go bad, it can affect the cruise control.

Can you compare them with the old lights? Maybe you’ll notice a difference between them?

If the brake switch were bad, I wouldn’t have any brake lights at all right?

I agree with Mikey here chase, prob just a coincidence you changing the lights and it not working. Brake lights can still work but cruise can go out...

I know this already... that’s the issue I’m having... lol. But again I verbalize that my cruise control worked perfectly with the other set of lights I had for the past two years. I will swap them back on because i have a long drive tomorrow, and I will take video showing it working with the old led tails.

I know this is the GMT800 platform area, but my 09 Tahoe cruise stopped working, and it was throwing a code for the brake switch before the engine blew up. The brake lights worked perfectly though.

That was what I was curious about. Lol. Thanks doe the heads up. I’ll pick one up and see if that changes anything.
