Such vehicles now use "fly by wire" or CANbus so the light unit is always powered and responds to the central computer (wherever that is) which in turn responds to the indicator lever however it chooses, not dependent in any way from it for power to continue operation.

I believe the OP is hijacking the signals. So he can read them, and decide what to do with his lights. In this case smart pixels, which are powered always the car is on.

We don't need no stinking' CANbus! Cannabis, maybe.

I hope you enjoyed the show!

I'm trying to wrap my head around how to add the functionality you showed to my sketch.

I've tried to insert it here with some naming changes of course.... Sure i'm doing something silly wrong.
