Tail light difference between 2017-2020 and 2021?

[Hi_Im_Mike]

Does anyone know if there is a difference? Is there a plug difference that would require an adapter to use?
For instance, let’s say my 2021 tail lights cracked and I wanted to buy a used set of 2020 would it be a simple plug and play or would I need an adapter for it to work? And vice versa?

Read all about it in the original AMER to EMEA/APAC conversion threads, and original vs refresh tailights threads.

The main differences to deal with is programming unless you dont mind a bit of spaghetti wiring and soldering.
Service Centers are not inclined to configure refresh tails on an older build date Model 3/Y or the older tails on a newer car.

One place to start:

Tail Light Retrofit- AMBER turn signal

One thing I've always hated about my 3 was how they use the Brake light as the turn signal. I'm a big believer in a dedicated color(amber) for turn signal. Unfortunately a lot of manufactures are going away from that in favor for the brake/turn combo. Maybe it's cost savings.IDK, but I am out...
