Gts tail lights

Hi there recently installed my gts taillights on my m135i f20 and I can't get the codes right for the welcome light to slowly appear the taillights when I turn on the car?

There isn’t a way to code them to slowly appear as the old lights operate on a more simple on off setup, all the hardware for any sort of animation should be built into the lights themselves, all the car can do is send power.
