So I've been having issues with my OEM passenger tail light. When signaling to turn only 2 lights would light up sequentially (the outside light does not blink; stays a light red). Also when locking the car, the outside light on the passenger side does not light up but lights up when unlocking...
I like it. It responds quickly as well as retain my steering wheel controls. It takes some time to customize it to your liking (background, launch app etc.) but you'll get the hang of it soon enough.
