I'm getting our new cars setup with a flash pattern that employs a solid red/blue front and low intensity slow flash rear.
After the car pulls over, turn that on and I use the stop light and takedowns depending on need.
I always shut down the front flashing lights because it is a requirement here during SFSTs and is a distraction to incoming cars and me when I look back.
