haha you stole my picture. but ya Im in love with them too. I might be buying a new A4 later this summer and would use my Jetta as a backup car. In was thinking of doing something similar to this
Audi S6 LED install for Volkswagen MkV R32 - Derek Punsalan - 5ThirtyOne
except I was going to buy some ecodes and take them apart and put them inside there. Also I was going to search for some smaller LEDs.
