so i have come to find that the more vital a light is , the more sensitive the carputer will be to detecting one out, reverse lights are much easier than brake lights, not all canbus are the same , if you look at canbus lights the resistors have numbers on them , that dictates their resistance , and as far as ive seen it doesnt go higher number = better it involves some research, i will however embark on this journey for us if you guys would like, its kind of my job..
