Yes, there was a first version but malfunctions were reported mainly due to improper installations with resistors and black box. The manufacturer of these tail lights (Vland) made a second version (the ones you have) of the same LED tail lights, in which it seems that no special installation is necessary. As you say, Plug and Play.
It is possible that these tail lights will pass the majority of MOTs in many European countries due to their high quality and that they meet all the required standards, but let me doubt they will pass the German TUV.
What I have just written has the importance that one wants to give it ...
What really matters is ...
My main interest was to know if they were authentic LED tail lights, that is, apart from being built with LEDs, the electrical/energy consumption was really low, but it is not like this with these LED tail lights.
This would allow me to stop the engine when stopped/parked without removing the keys from the ignition switch but with the sidelights ON (light switch on Auto or headlights, not the side lights position) without having to worry about power consumption (battery drain) for a long period of time. There is a Bit in the BCM to code this energy transition.
