Also inquiring if they fit

I was also interested if this will be possible. The dimensions look similar.

Yes especially since the factory Tahoe lights have none LED backup lights.

Do these have the animation as well?

Yes they have a start up animation

I ordered a 2025 Tahoe LS Tail light from the local dealer. Unfortunately the plug/harness is completely different from the 2021-2024. It is a wider plug and to adapt to a 2021-2024, we will likely need a custom harness built.

That stinks. Well, maybe the aftermarket will start making good clones soon with pre-‘25 harnesses.

Thanks for sharing, sorry it didn’t work out for you (and all of us!)

It wouldn’t surprise me if the plug under the bumper/back of the truck is the same in the 25 as 21-24 and you just need the short harness that goes from there up to the tail light to get it to plug in. Note that there is a chance that you would need to add a resistor or two to compensate for LED vs incandescent bulbs used in 21-24 Tahoes & Suburbans.

I was thinking the same thing(s).
