Do it.
You'll need a sympathetic MOT guy or just keep the originals and chuck them in once a year.
It's not a complicated job at all, and you don't need a "mate to help you with the bumper" like all the YouTube videos say; just chuck the packaging from the new lights on the ground for some extra safety. (Making no presumptions on your skills and knowledge, just putting it out there).
I'll try to find the Ali shop where I bought mine (I've got a few accounts there now). Obvs no guarantees they'll behave the same as mine, but with all these coding and tax gambles you want the dice at least a little weighted!
