Exactly! It was literally plug and play. The hardest part was disassembling the mirror. Link here.
Edit: if you want a guide on how I did it, I can write one up. It wasn’t that hard, but it took me a while to find a helpful YT video.

I got some Chinese ones from Amazon (so something similar to those Aliexpress ones) but smoked so they blend in even more when off (Carbon steel grey and Pinnaloy forged carbon fiber caps). Personally I love the understated look and they're bright af tbh when in operation. They also have other options like transparent which are closer to the Osram I guess.

One thing to note is that the light doesn't extend into the little square that's inside the mirror that you can see while driving (OEM just let's light bleed through that hole to show when the light is on). It's not a dealbreaker to me since you still have the turnsignals on inside the car, plus the sound.
