Tagging on to this, I have enabled the pace car indicators on my car, but the halves of the light still do their little bit sequentially, if that makes sense? At first I thought this was a side effect of it being a 7.5, and that the modules just were sequential and that's the best I could get.
However, I recently noticed that when I unlock the car, the first flash of the inner half, the whole light comes on together rather than sequentially. Is there further coding to get them to do this all the time?
