Yes, I'm working on "plug and play" units.
Each tail lamp assembly with have it's own nano, mini 5 way relay board, and 12-5v converter so it can just plug into the original wiring and work.
I'll do custom styles / options for people, different animations sequences, colors etc.
It's awesome to be able to integrate my CAD / 3d printing work with these new skills. The possibilities are endless 
The next part of this project would be able to upload / change patterns over bluetooth!
